Misc updates for mlx5 driver 1) Add TX max rate support for MQPRIO channel mode 2) Trivial TC action and modify header refactoring 3) TC support for accept action in fdb offloads 4) Allow single IRQ for PCI functions 5) Bridge offload: Pop PVID VLAN header on egress miss Vlad Buslov says: ================= With current architecture of mlx5 bridge offload it is possible for a packet to match in ingress table by source MAC (resulting VLAN header push in case of port with configured PVID) and then miss in egress table when destination MAC is not in FDB. Due to the lack of hardware learning in NICs, this, in turn, results packet going to software data path with PVID VLAN already added by hardware. This doesn't break software bridge since it accepts either untagged packets or packets with any provisioned VLAN on ports with PVID, but can break ingress TC, if affected part of Ethernet header is matched by classifier. Improve compatibility with software TC by restoring the packet header on egress miss. Effectively, this change implements atomicity of mlx5 bridge offload implementation - packet is either modified and redirected to destination port or appears unmodified in software. ================= -----BEGIN PGP SIGNATURE----- iQEzBAABCAAdFiEEGhZs6bAKwk/OTgTpSD+KveBX+j4FAmFbpiEACgkQSD+KveBX +j4rjQf/a1UTqBH31Rh3+zr71yAhfsEYHdSogdPe1oo9zA4IvDZ0uwwdBNPNjzYa ZTcDPKmHgbi6UUqokpmWHYDieXNsZz95lPWS0/QcySgnSag9keGpS2I1y9KtvurH MkejWuCUD1UniPPIw02F1AJ3hNOLjDst8gydyt2T52lqxHX9xprcgxAXcUPkGCsW 7jw+g5F6hbahgh1fFdBERqdLmvJiv2i0gmo5XEIYr5lQePqba43B4EQNKZkSQ/91 Gz8537wCHixW4q2e81m60b0olXrG65JTQAj+ckUUR8VbHwxCBbM5jzOZZXw9FXbB hebTL+GflwbmshVWluXLlSKLu2gBaw== =iVdj -----END PGP SIGNATURE----- Merge tag 'mlx5-updates-2021-10-04' of git://git.kernel.org/pub/scm/linux/kernel/git/saeed/linux Saeed Mahameed says: ==================== mlx5-updates-2021-10-04 Misc updates for mlx5 driver 1) Add TX max rate support for MQPRIO channel mode 2) Trivial TC action and modify header refactoring 3) TC support for accept action in fdb offloads 4) Allow single IRQ for PCI functions 5) Bridge offload: Pop PVID VLAN header on egress miss Vlad Buslov says: ================= With current architecture of mlx5 bridge offload it is possible for a packet to match in ingress table by source MAC (resulting VLAN header push in case of port with configured PVID) and then miss in egress table when destination MAC is not in FDB.

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
