2016-12-06i40e: defeature support for PTP L4 frame detection on XL710Jacob Keller
A product decision has been made to defeature detection of PTP frames over L4 (UDP) on the XL710 MAC. Do not advertise support for L4 timestamping.

2016-12-06i40e: lock service task correctlyMitch Williams
The service task lock was being set in the scheduling function, not the actual service task. This would potentially leave the bit set for a long time before the task actually ran. Furthermore, if the service task takes too long, it calls the schedule function to reschedule itself - which would fail to take the lock and do nothing. Instead, set and clear the lock bit in the service task itself. In the process, get rid of the i40e_service_event_complete() function, which is really just two lines of code that can be put right in the service task itself.

Add support for 25G devices - defines and data structures.

This change creates a macro and uses it to increment the 25G PHY values when creating 25G bitfields.

2016-12-06i40e: remove code to handle dev_addr speciallyJacob Keller
The netdev->dev_addr MAC filter already exists in the MAC/VLAN hash table, as it is added when we configure the netdev in i40e_configure_netdev. Because we already know that this address will be updated in the hash_for_each loops, we do not need to handle it specially. This removes duplicate code and simplifies the i40e_vsi_add_vlan and i40e_vsi_kill_vlan functions. Because we know these filters must be part of the MAC/VLAN hash table, this should not have any functional impact on what filters are included and is merely a code simplification.

2016-12-06i40e: restore workaround for removing default MAC filterJacob Keller
A previous commit 53cb6e9e8949 ("i40e: Removal of workaround for simple MAC address filter deletion") removed a workaround for some firmware versions which was reported to not be necessary in production NICs. Unfortunately this workaround is necessary in some configurations, specifically the Ethernet Controller XL710 for 40GbE QSFP+ (8086:1583). Without this patch, the mentioned NICs with current firmware exhibit issues when adding VLANs, as outlined by the following reproduction: $modprobe i40e $ip link set <device> up $ip link add link <device> vlan100 type vlan id 100 $dmesg | tail <snip> kernel: i40e 0000:82:00.0: Error I40E_AQ_RC_EINVAL adding RX filters on PF, promiscuous mode forced on This results in filters being marked as FAILED and setting the device in promiscuous mode. The root cause of receiving the -EINVAL error response appears to be due to a conflict with the default MAC filter which still exists on the default firmware for this device. Attempting to add a new VLAN filter on the default MAC address conflicts with the IGNORE_VLAN setting on the default rule.

2016-12-06tun: Use netif_receive_skb instead of netif_rxAndrey Konovalov
This patch changes tun.c to call netif_receive_skb instead of netif_rx when a packet is received (if CONFIG_4KSTACKS is not enabled to avoid stack exhaustion). The difference between the two is that netif_rx queues the packet into the backlog, and netif_receive_skb proccesses the packet in the current context. This patch is required for syzkaller [1] to collect coverage from packet receive paths, when a packet being received through tun (syzkaller collects coverage per process in the process context). As mentioned by Eric this change also speeds up tun/tap. As measured by Peter it speeds up his closed-loop single-stream tap/OVS benchmark by about 23%, from 700k packets/second to 867k packets/second. A similar patch was introduced back in 2010 [2, 3], but the author found out that the patch doesn't help with the task he had in mind (for cgroups to shape network traffic based on the original process) and decided not to go further with it. The main concern back then was about possible stack exhaustion with 4K stacks.

2016-12-06net: hns: Fix to conditionally convey RX checksum flag to stackSalil
This patch introduces the RX checksum function to check the status of the hardware calculated checksum and its error and appropriately convey status to the upper stack in skb->ip_summed field. In hardware, we only support checksum for the following protocols: 1) IPv4, 2) TCP(over IPv4 or IPv6), 3) UDP(over IPv4 or IPv6), 4) SCTP(over IPv4 or IPv6) but we support many L3(IPv4, IPv6, MPLS, PPPoE etc) and L4(TCP, UDP, GRE, SCTP, IGMP, ICMP etc.) protocols. Hardware limitation: Our present hardware RX Descriptor lacks L3/L4 checksum "Status & Error" bit (which usually can be used to indicate whether checksum was calculated by the hardware and if there was any error encountered during checksum calculation). Software workaround: We do get info within the RX descriptor about the kind of L3/L4 protocol coming in the packet and the error status. These errors might not just be checksum errors but could be related to version, length of IPv4, UDP, TCP etc. Because there is no-way of knowing if it is a L3/L4 error due to bad checksum or any other L3/L4 error, we will not (cannot) convey hardware checksum status(CHECKSUM_UNNECESSARY) for such cases to upper stack and will not maintain the RX L3/L4 checksum counters as well.

2016-12-05net: ep93xx_eth: Do not crash unloading moduleFlorian Fainelli
When we unload the ep93xx_eth, whether we have opened the network interface or not, we will either hit a kernel paging request error, or a simple NULL pointer de-reference because: - if ep93xx_open has been called, we have created a valid DMA mapping for ep->descs, when we call ep93xx_stop, we also call ep93xx_free_buffers, ep->descs now has a stale value - if ep93xx_open has not been called, we have a NULL pointer for ep->descs, so performing any operation against that address just won't work Fix this by adding a NULL pointer check for ep->descs which means that ep93xx_free_buffers() was able to successfully tear down the descriptors and free the DMA cookie as well.

Do not open code getting the MAC address exclusively from the "local-mac-address" property, but instead use of_get_mac_address() which looks up the MAC address using the 3 typical property names.

2016-12-05net: ethoc: Account for duplex changesFlorian Fainelli
ethoc_mdio_poll() which is our PHYLIB adjust_link callback does nothing, we should at least react to duplex changes and change MODER accordingly. Speed changes is not a problem, since the OpenCores Ethernet core seems to be reacting okay without us telling it.

2016-12-05bnx2x: Prevent tunnel config for 577xxMintz, Yuval
Only the 578xx adapters are capable of configuring UDP ports for the purpose of tunnelling - doing the same on 577xx might lead to a firmware assertion. We're already not claiming support for any related feature for such devices, but we also need to prevent the configuration of the UDP ports to the device in this case.

2016-12-05bnx2x: Correct ringparam estimate when DOWNMintz, Yuval
Until interface is up [and assuming ringparams weren't explicitly configured] when queried for the size of its rings bnx2x would claim they're the maximal size by default. That is incorrect as by default the maximal number of buffers would be equally divided between the various rx rings. This prevents the user from actually setting the number of elements on each rx ring to be of maximal size prior to transitioning the interface into up state. To fix this, make a rough estimation about the number of buffers. It wouldn't always be accurate, but it would be much better than current estimation and would allow users to increase number of buffers during early initialization of the interface.
