2017-09-13be2net: fix TSO6/GSO issue causing TX-stall on Lancer/BExSuresh Reddy
IPv6 TSO requests with extension hdrs are a problem to the Lancer and BEx chips. Workaround is to disable TSO6 feature for such packets. Also in Lancer chips, MSS less than 256 was resulting in TX stall. Fix this by disabling GSO when MSS less than 256. Signed-off-by: Suresh Reddy <suresh.reddy@broadcom.com> Signed-off-by: David S.

2017-04-18be2net: VxLAN offload should be re-enabled when only 1 UDP port is leftSriharsha Basavapatna
We disable VxLAN offload when more than 1 UDP port is added to the driver, since Skyhawk doesn't support offload with multiple ports. The existing driver design expects the user to delete all port configurations and create a configuration with a single UDP port for VxLAN offload to be re-enabled. Remove this restriction by tracking the ports added and re-enabling offload when ports get deleted and only 1 port is left.

2016-09-07be2net: Fix mac address collision in some configurationsSuresh Reddy
If the device mac address is updated using ndo_set_mac_address(), while the same mac address is already programmed, the driver does not detect this condition if its netdev->dev_addr has been changed. The driver tries to add the same mac address resulting in mac address collision error. This has been observed in bonding mode-5 configuration. To fix this, store the mac address configured in HW in the adapter structure. Use this to compare against the new address being updated to avoid collision.

2016-09-07be2net: Support UE recovery in BEx/Skyhawk adaptersSriharsha Basavapatna
This patch supports recovery from UEs caused due to Transient Parity Errors (TPE), in BE2, BE3 and Skyhawk adapters. This change avoids system reboot when such errors occur. The driver recovers from these errors such that the adapter resumes full operational status as prior to the UE. Following is the list of changes in the driver to support this: o The driver registers its UE recoverable capability with ARM FW at init time. This also allows the driver to know if the feature is supported in the FW. o As the UE recovery requires precise time bound processing, the driver creates its own error recovery work queue with a single worker thread (per module, shared across functions). o Each function runs an error detection task at an interval of 1 second as required by the FW. The error detection logic already exists for BEx/SH, but it now runs in the context of a separate worker thread. o When an error is detected by the task, if it is recoverable, the PF0 driver instance initiates a soft reset, while other PF driver instances wait for the reset to complete and the chip to become ready. Once the chip is ready, all driver instances including PF0, resume to reinitialize the respective functions. o The PF0 driver checks for some recovery criteria, to determine if the recovery can be initiated. If the criteria is not met, the PF0 driver does not initiate a soft reset, it retains the existing behavior to stop further processing and requires a reboot to get the chip to operational state again. o To allow each function to share the workq, while also making progress in its recovery process, a per-function recovery state machine is used. The per-function tasks avoid blocking operations like msleep() while in this state machine (until reinit state) and instead reschedule for the required delay. o With these changes, the existing error recovery code for Lancer also runs in the context of the new worker thread.

2016-08-08be2net: replace polling with sleeping in the FW completion pathSathya Perla
The ndo_set_rx_mode() and ndo_add/del_vxlan_port() calls may be called with BHs disabled. The driver currently issues the required cmds to the FW in these contexts and polls on completions from the FW, while BHs remain disabled. This can cause either packet loss or packet reception to be delayed on that CPU. This patch defers processing of the above cmds to a separate workqueue. With this change, FW cmds are now issued only in process context. Now that the FW cmds are issued only in process context, they can sleep waiting for a completion instead of polling. All the spin_lock_bh(mcc_lock) calls are now replaced with mutex calls. Also a new rx_filter_lock is now needed to protect the RX filtering fields like vids[] between be_vlan_add/rem_vid() and __be_set_rx_mode() contexts.

2016-08-08be2net: Avoid unnecessary firmware updates of multicast listSriharsha Basavapatna
Eachtime the ndo_set_rx_mode() routine is called, the driver programs the multicast list in the adapter without checking if there are any changes to the list. This leads to a flood of RX_FILTER cmds when a number of vlan interfaces are configured over the device, as the ndo_ gets called for each vlan interface. To avoid this, we now use __dev_mc_sync() and __dev_uc_sync() API, but only to detect if there is a change in the mc/uc lists. Now that we use this API, the code has to be-designed to issue these API calls for each invocation of the be_set_rx_mode() call.

This patch now allows a combination of RX/TX-only channels along with combined channels. N TX-queues and M RX-queues can be created with the following cmds: ethtool -L ethX combined N rx M-N (when N < M) ethtool -L ethX combined M tx N-M (when M < N) Setting both RX-only and TX-only channels is still not supported.

2016-06-07be2net: Fix provisioning of RSS for VFs in multi-partition configurationsSomnath Kotur
Currently, we do not distribute queue resources to enable RSS for VFs in multi-channel/partition configurations. Fix this by having each PF(SRIOV capable) calculate it's share of the 15 RSS Policy Tables available per port before provisioning resources for all the VFs. This proportional share calculation is done based on division of the PF's MAX VFs with the Total MAX VFs on that port. It also needs to learn about the no: of NIC PFs on the port and subtract that from the 15 RSS Policy Tables on the port.

In QnQ configurations like Flex-10 where the VLANs are inserted by the ASIC, on rare occasions the HW is encountering a scenario where the final frame length ends to be greater than what the ASIC can support. This is because when the TXULP pulls the TX WRB to check the length of the frame to be transmitted it also adds the size of VLANs to be inserted by the HW to the length of the frame indicated in the WRB, which in some cases fails the range check. This causes a UE. Avoid this by trimming the skb length to accommodate the VLAN insertion. Signed-off-by: Ajit Khaparde <ajit.khaparde@broadcom.com> Signed-off-by: David S.

2016-02-07be2net: SRIOV Queue distribution should factor in EQ-count of VFsSriharsha Basavapatna
The SRIOV resource distribution logic for RX/TX queue counts is not optimal when a small number of VFs are enabled. It does not take into account the VF's EQ count while computing the queue counts. Because of this, the VF gets a large number of queues, though it doesn't have sufficient EQs, resulting in wasted queue resources. And the PF gets a smaller share of queues though it has more EQs.

2015-12-28RDMA/be2net: Remove open and close entry pointsDevesh Sharma
Recently Dough Ledford reported a deadlock happening between ocrdma-load sequence and NetworkManager service issueing "open" on be2net interface. The deadlock happens when any be2net hook (e.g. open/close) is called in parallel to insmod ocrdma.ko. A. be2net is sending administrative open/close event to ocrdma holding device_list_mutex. It does this from ndo_open/ndo_stop hooks of be2net. So sequence of locks is rtnl_lock---> device_list lock B. When new ocrdma roce device gets registered, infiniband stack now takes rtnl_lock in ib_register_device() in GID initialization routines. So sequence of locks in this path is device_list lock ---> rtnl_lock. This improper locking sequence causes deadlock. In order to resolve the above deadlock condition, ocrdma intorduced a patch to stop listening to administrative open/close events generated from be2net driver. It now depends on link-state-change async-event generated from CNA. This change leaves behind dead code which used to generate administrative open/close events. This patch cleans-up all that dead code from be2net.

OS2BMC feature will allow the server to communicate with the on-board BMC/idrac (Baseboard Management Controller) over the LOM via standard Ethernet. When OS2BMC feature is enabled, the LOM will filter traffic coming from the host. If the destination MAC address matches the iDRAC MAC address, it will forward the packet to the NC-SI side band interface for iDRAC processing. Otherwise, it would send it out on the wire to the external network. Broadcast and multicast packets are sent on the side-band NC-SI channel and on the wire as well. Some of the packet filters are not supported in the NIC and hence driver will identify such packets and will hint the NIC to send those packets to the BMC. This is done by duplicating packets on the management ring. Packets are sent to the management ring, by setting mgmt bit in the wrb header. The NIC will forward the packets on the management ring to the BMC through the side-band NC-SI channel.

It split functions in half and moved them around, when the real actual conflict only existed solely inside of one function, that being be_map_pci_bars(). So instead, to resolve this, I checked out be_main.c from the top of net-next, then I applied the be_main.c changes from 'net' since the last time I merged. And this worked beautifully. The inet_diag.c and sysctl_net_core.c conflicts were simple overlapping changes, and were easily to resolve. Signed-off-by: David S. Miller <davem@davemloft.net>
2015-03-20be2net: use PCI MMIO read instead of config read for errorsSuresh Reddy
When an EEH error occurs, the device/slot is disconnected. This condition is more reliably detected (i.e., returns all ones) with an MMIO read rather than a config read -- especially on power platforms. Hence, this patch fixes EEH error detection by replacing config reads with MMIO reads for reading the error registers. The error registers in Skyhawk-R/BE2/BE3 are accessible both via the config space and the PCICFG (BAR0) memory space.

2015-03-20be2net: Prevent VFs from enabling VLAN promiscuous modeVasundhara Volam
Currently, a PF does not restrict its VF interface from enabling vlan promiscuous mode. This breaks vlan isolation when a vlan (transparent tagging) is configured on a VF. This patch fixes this problem by disabling the vlan promisc capability for VFs.

2015-03-04be2net: re-distribute SRIOV resources allowed by FWVasundhara Volam
When SR-IOV is enabled in the adapter, the FW distributes resources evenly across the PF and it's VFs. This is currently done only for some resources. This patch adds support for a new cmd that queries the FW for the list of resources for which the distribution is allowed and distributes them accordingly.

2015-03-04be2net: avoid creating the non-RSS default RXQ if FW allows toVasundhara Volam
On BE2, BE3 and Skhawk-R chips one non-RSS (called "default") RXQ was needed to receive non-IP traffic. Some FW versions now export a capability called IFACE_FLAGS_DEFQ_RSS where this requirement doesn't hold. On such FWs the driver now does not create the non-RSS default queue. This prevents wasting one RXQ per VF. Signed-off-by: Vasundhara Volam <vasundhara.volam@emulex.com> Signed-off-by: Sathya Perla <sathya.perla@emulex.com> Signed-off-by: David S.
