2020-05-28vmxnet3: add support to get/set rx flow hashRonak Doshi
With vmxnet3 version 4, the emulation supports multiqueue(RSS) for UDP and ESP traffic. A guest can enable/disable RSS for UDP/ESP over IPv4/IPv6 by issuing commands introduced in this patch. ESP ipv6 is not yet supported in this patch. This patch implements get_rss_hash_opts and set_rss_hash_opts methods to allow querying and configuring different Rx flow hash configurations.

2020-05-28ice: Refactor VF VSI release and setup functionsBrett Creeley
Currently when a VF VSI calls ice_vsi_release() and ice_vsi_setup() it subsequently clears/sets the VF cached variables for lan_vsi_idx and lan_vsi_num. This works fine, but can be improved by handling this in the VF specific VSI release and setup functions. Also, when a VF VSI is setup too many parameters are passed that can be derived from the VF. Fix this by only calling VF VSI setup with the bare minimum parameters. Also, add functionality to invalidate a VF's VSI when it's released and/or setup fails. This will make it so a VF VSI cannot be accessed via its cached vsi_idx/vsi_num in these cases. Finally when a VF's VSI is invalidated set the lan_vsi_idx and lan_vsi_num to ICE_NO_VSI to clearly show that there is no valid VSI associated with this VF.

2020-05-28ice: Refactor VF resetBrett Creeley
Currently VF VSI are being reset twice during a PFR or greater. This is causing reset, specifically resetting all VFs, to take too long. This is causing various issues with VF drivers not being able to gracefully handle the VF reset timeout. Fix this by refactoring how VF reset is handled for the case mentioned previously and for the VFR/VFLR case. The refactor was done by doing the following: 1. Removing the call to ice_vsi_rebuild_by_type for ICE_VSI_VF VSI, which was causing the initial VSI rebuild. 2. Adding functions for pre/post VSI rebuild functions that can be called in both the reset all VFs case and reset individual VF case. 3. Adding VSI rebuild functions that are specific for the reset all VFs case and adding functions that are specific for the reset individual VF case. 4. Calling the pre-rebuild function, then the specific VSI rebuild function based on the reset type, and then calling the post-rebuild function to handle VF resets. This patch series makes some assumptions about how VSI are handling by FW during reset: 1. During a PFR or greater all VSI in FW will be cleared. 2. During a VFR/VFLR the VSI rebuild responsibility is in the hands of the PF software. 3. There is code in the ice_reset_all_vfs() case to amortize operations if possible. This was left intact. 4. PF software should not be replaying VSI based filters that were added other than host configured, PF software configured, or the VF's default/LAA MAC. This is the VF drivers job after it has been reset.

2020-05-28ice: fix kernel BUG if register_netdev failsJacob Keller
If register_netdev() fails, the driver will attempt to cleanup the q_vectors and inadvertently trigger a kernel BUG due to a NULL pointer dereference. This occurs because cleaning up q_vectors attempts to call netif_napi_del on napi_structs which were never initialized. Resolve this by releasing the netdev in ice_cfg_netdev and setting vsi->netdev to NULL. This ensures that after ice_cfg_netdev fails the state is rewound to match as if ice_cfg_netdev was never called.

2020-05-28ice: fix potential double free in probe unrollingJacob Keller
If ice_init_interrupt_scheme fails, ice_probe will jump to clearing up the interrupts. This can lead to some static analysis tools such as the compiler sanitizers complaining about double free problems. Since ice_init_interrupt_scheme already unrolls internally on failure, there is no need to call ice_clear_interrupt_scheme when it fails. Add a new unroll label and use that instead.

Jesse fixes a number of issues, starting with fixing the remaining signed versus unsigned comparison issues. Cleaned up an unused code define. Fixed the implementation of the manage MAC write command, to simplify it by using a simple array to represent the MAC address when writing it. Paul fixes the setting of the VF default LAN address, by removing a check that assumed that the address had been deleted and zeroed. Surabhi prevents a memory leak on filter management initialization failures and during queue initialization and buffer allocation failures. Brett adds additional receive error counters that are reported by ethtool. Fixed the enabling and disabling of VLAN stripping when the PVID has been set. Evan fixes a race condition between the firmware and software, which can occur between the admin queue setup and the first command sent. Marta fixes the driver when XDP transmit rings are destroyed, also make sure the XDP transmit queues are also destroyed. Update the statistics when XDP transmit programs are loaded and packets are sent. Changed the number of XDP transmit queues to match the number of receive queues, instead of matching the number of transmit queues. Bruce avoids undefined behavior by not writing the 8-bit element init_q_state with the associated internal-to-hardware field which is 122-bits. Anirudh (Ani) refactors the receive checksum checks. Krzysztof notifies the user if the fill queue is not long enough to prepare all buffers before packet processing starts and allocates the buffers during the NAPI poll. ==================== Signed-off-by: David S.

This occurs because there is no knowledge at eswitch level of the stand-by representor device. Solution: --------- Using standard bonding driver, a bond netdevice is created over VF representor device which is used for offloading tc rules. Two VF representors are bonded together, one for the passthrough VF device and another one for the stand-by VF device. With this solution, mlx5 driver listens to the failover events occuring at the bond device level to failover traffic to either of the active VF representor of the bond. a. VM with netfailover device of VF pass-thru (PT) device and virtio-net paravirtualized device with same MAC-address to handle failover traffics at VM level. b. Host bond is active-standby mode, with the lower devices being the VM VF PT representor, and the representor of the 2nd VF to handle failover traffics at Hypervisor/V-Switch OVS level. - During the steady state (fast datapath): set the bond active device to be the VM PT VF representor. - During failover: apply bond failover to the second VF representor device which connects to the VM non-accelerated path. c. E-Switch ingress/egress ACL tables to support failover traffics at E-Switch level I. E-Switch egress ACL with forward-to-vport rule: - By default, eswitch vport egress acl forward packets to its counterpart NIC vport. - During port failover, the egress acl forward-to-vport rule will be added to e-switch vport of passive/in-active slave VF representor to forward packets to other e-switch vport ie. the active slave representor's e-switch vport to handle egress "failover" traffics. - Using lower change netdev event to detect a representor is a lower dev (slave) of bond and becomes active, adding egress acl forward-to-vport rule of all other slave netdevs to forward to this representor's vport. - Using upper change netdev event to detect a representor unslaving from bond device to delete its vport's egress acl forward-to-vport rule. II. E-Switch ingress ACL metadata reg_c for match - Bonded representors' vorts sharing tc block have the same root ingress acl table and a unique metadata for match. - Traffics from both representors's vports will be tagged with same unique metadata reg_c. - Using upper change netdev event to detect a representor enslaving/unslaving from bond device to setup shared root ingress acl and unique metadata. 2) From Alex Vesker (2): Slpit RX and TX lock for parallel rule insertion in software steering 3) Eli Britstein (2): Optimize performance for IPv4/IPv6 ethertype use the HW ip_version register rather than parsing eth frames for ethertype. ==================== Signed-off-by: David S.

First generation has 10 shapers, freely assignable to any of the 4 external ports and 8 traffic classes, and second generation has 16 shapers.

2020-05-28mt76: fix wcid allocation issuesFelix Fietkau
mt76 core uses ffs() to find the next free bit. This works well for 32 bit architectures where BITS_PER_LONG is 32. ffs only checks 32 bit values, so allocation fails on 64 bit architectures. Additionally, the wcid mask array was too small in cases where the array was not a multiple of BITS_PER_LONG. Fix this by making the wcid mask array u32 instead and use DIV_ROUND_UP for the size, just in case we ever bump it to a value that's not a multiple of 32.
