This series includes updates for mlx5e netdev driver. 1) Allowr flow based VF vport mirroring under sriov switchdev scheme, added support for offloading the TC mirred mirror sub-action, from Chris Mi. ================= From: Or Gerlitz <ogerlitz@mellanox.com> The user will typically set the actions order such that the mirror port (mirror VF) sees packets as the original port (VF under mirroring) sent them or as it will receive them. In the general case, it means that packets are potentially sent to the mirror port before or after some actions were applied on them. To properly do that, we follow on the exact action order as set for the flow and make sure this will also be the case when we program the HW offload. If all the actions should apply before forwarding to the mirror and dest port, mirroring is just multicasting to the two vports. Otherwise, we split the TC flow to two HW rules, where the 1st applies only the actions needed up to the mirror (if there are such) and the 2nd the rest of the actions plus the forwarding to the dest vport. ================= 2) Move to order-0 only allocations (using fragmented work queues) for all work queues used by the driver, RX and TX descriptor rings (RQs, SQs and Completion Queues (CQs)), from Tariq Toukan. 3) Avoid resetting netdevice statistics on netdevice state changes, from Eran Ben Elisha. -----BEGIN PGP SIGNATURE----- iQEcBAABAgAGBQJbCKCcAAoJEEg/ir3gV/o++7sH/1FPmwvpf4qNEsusr714lNnl PxzVjnwxKZNYyovIjr6QGSxMM1qDiPejyYnZIAzH00B+XWCq3zn8H3sfJLFbmxN3 clayd6dGV27HzLZwV2aD9vXfVb7snNhQtTp5zoajsnZY4xO335n3FA3kF5TxLqKO bxsnY2xSaSpbrBH2z2UvHc+ib9KnvY1Q+gr2WqdRnN5Tm51Zq+bgaUw0nROefGJK XR/aVBub3PsjA8W/0/b3DGfiP1bgPeU6QmLhdjn3IEufFtbEJH+K/4u53l3A4RLR fXmJrWKlZn8j7LUBFOD0/G43RU/YzqRgwF/iUwCxbUU2wK/J0cPv23drLDVYzaY= =n7Zz -----END PGP SIGNATURE----- Merge tag 'mlx5e-updates-2018-05-25' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5e-updates-2018-05-25 This series includes updates for mlx5e netdev driver. 1) Allowr flow based VF vport mirroring under sriov switchdev scheme, added support for offloading the TC mirred mirror sub-action, from Chris Mi. ================= From: Or Gerlitz <ogerlitz@mellanox.com> The user will typically set the actions order such that the mirror port (mirror VF) sees packets as the original port (VF under mirroring) sent them or as it will receive them.
