[GIT PULL] Please pull RDMA subsystem changes

Hi Linus,

As seems to be typical, this is a smaller PR probably due to the
holidays, but also normalish for RDMA right now. The new ROCEv2 support
for ERDMA stands out as the largest functional change.

There are some non-trivial merge conflicts with the RDMA -rc branch,
it took a couple of rounds with Stephen to get things sorted, but this
is what has been in linux-next for a while now.

    https://lore.kernel.org/r/20250106105106.3d94b0c3@canb.auug.org.au
    https://lore.kernel.org/r/20250106120252.000a2afa@canb.auug.org.au
    https://lore.kernel.org/r/20250106111307.7d0f55ba@canb.auug.org.au

I've also prepared the tag for-linus-merged with the agreed linux-next
merge resolution using v6.13 that you may prefer to pull instead of
this unmerged tag.

Otherwise, here is git show of my merge commit, which matches
linux-next, for reference:

  RDMA/mlx5: Fix implicit ODP use after free (2025-01-21 14:10:49 -0400)

----------------------------------------------------------------
RDMA v6.14 merge window pull request

Lighter that normal, but the now usual collection of driver fixes and
small improvements:

- Small fixes and minor improvements to cxgb4, bnxt_re, rxe, srp, efa,
  cxgb4

- Update mlx4 to use the new umem APIs, avoiding direct use of scatterlist

- Support ROCEv2 in erdma

- Remove various uncalled functions, constify bin_attribute

- Provide core infrastructure to catch netdev events and route them to
  drivers, consolidating duplicated driver code

- Fix rare race condition crashes in mlx5 ODP flows
