mlx5: extend mlx5_ib_create_cq struct with fields from the current Linux ABI

2026-07-07T11:24:11+00:00

This is backward ABI-compatible, because the only place in kernel that
uses the structure, namely the mlx5_ib_cq.c:mlx5_ib_create_cq()
function, copies in as much structure members as provided by userspace.

OFED: Calculate UDP source port based on flow label or lqpn/rqpn

2026-06-24T19:30:56+00:00

Calculate and set UDP source port based on the flow label. If flow label
is not defined in GRH then calculate it based on lqpn/rqpn.

OFED: Various changes from Linux 4.19

2026-06-24T19:30:56+00:00

Many of these changes deal with shifting from fetcing SGID attributes
via an index in drivers to including references to SGID attributes in
other structures passed to driver callbacks which can be used directly
avoiding the need for fetching attributes via lookup functions.  I had
to fixup the ROCE GID management code directly as the version in
FreeBSD is very different from Linux.

I also tweaked the change from commit
475c8de7bf2dc86d9806709a04e9c8f524d4ec32 to use a goto to reduce diffs
with upstream to minimize conflicts when merging upstream changes.

This contains changes from the following Linux commits:

Parts of 1060f8653414 were already merged into FreeBSD.  Cosmetic
changes made in rdma_addr_find_l2_eth_by_grh while merging this change
were just to reduce the diff with Linux to ease merging future
changes.

The merge of 56d0a7d9a0f0 differs slightly from the Linux commit as
FreeBSD was missing the original changes to check for link-local
addresses in ib_resolve_eth_dmac.

The merge of 2493a57bc10f is mostly a cosmetic change to reduce diffs
with upstream as local changes in FreeBSD passed the dev_addr as the
last argument instead of the dev_type and if_index already.
