Subject: [GIT PULL] Please pull RDMA subsystem changes
Hi Linus,
Much larger pull request this time. We got a new Pensando ionic
driver, a new Gen 3 HW support for Intel irdma, and lots of small
bnxt_re improvements. Plus the usual little driver fixes all over.
There are two or three more new drivers on the list so I expect a few
more larger merge windows going forward.
The merge conflict is resolved as Stephen did:
https://lore.kernel.org/r/20250911122330.14834c0a@canb.auug.org.au
Keep bnxt_re_free_gid_ctx() and move it ahead of
bnxt_re_get_stats_ctx(), bnxt added their new functions to the same
spot in the rc and next branches.
The tag for-linus-merged with my merge resolution to v6.17 is also
available to pull.
Thanks,
Jason

RDMA/ionic: Fix memory leak of admin q_wr (2025-09-26 13:12:56 -0300)
----------------------------------------------------------------
RDMA v6.18 merge window pull request
A new Pensando ionic driver, a new Gen 3 HW support for Intel irdma,
and lots of small bnxt_re improvements.
- Small bug fixes and improves to hfi1, efa, mlx5, erdma, rdmarvt, siw
- Allow userspace access to IB service records through the rdmacm
- Optimize dma mapping for erdma
- Fix shutdown of the GSI QP in mana
- Support relaxed ordering MR and fix a corruption bug with mlx5 DMA Data
Direct
- Many improvement to bnxt_re:
* Debugging features and counters
* Improve performance of some commands
* Change flow_label reporting in completions
* Mirror vnic
* RDMA flow support
- New RDMA driver for Pensando Ethernet devices: ionic
- Gen 3 hardware support for the Intel irdma driver
- Fix rdma routing resolution with VRFs
