Subject: [GIT PULL][mlx5-next 0/4] Cached vhca id and adjacent function vports

From: Saeed Mahameed <saeedm@...dia.com>

Hi Jakub, Jason,

This pull request introduces a preparation patchset for caching vhca_id 
and needed HW bits for the upcoming netdev/eswitch series to support
adjacent function vports.

For more information please see tag log below.

The following changes since commit 8f5ae30d69d7543eee0d70083daf4de8fe15d585:

  {rdma,net}/mlx5: export mlx5_vport_get_vhca_id (2025-08-15 12:17:47 -0700)

----------------------------------------------------------------
mlx5-next-vhca-id

A preparation patchset for adjacent function vports.

Adjacent functions can delegate their SR-IOV VFs to sibling PFs,
allowing for more flexible and scalable management in multi-host and
ECPF-to-host scenarios. Adjacent vports can be managed by the management
PF via their unique vhca id and can't be managed by function index as the
index can conflict with the local vports/vfs.

This series provides:

- Use the cached vcha id instead of querying it every time from fw
- Query hca cap using vhca id instead of function id when FW supports it
- Add HW capabilities and required definitions for adjacent function vports
