[PATCH v2 0/3] net/mlx5: SF/representor hotplug fixes

[Max Tottenham]

This series fixes several issues encountered when hotplugging SF
devices and their representors at runtime.

Patch 1 fixes ROCE disable for auxiliary (SF) devices by using the
correct devlink attributes (auxiliary bus + device name) instead of
incorrectly targeting the parent PF.

Patch 2 ensures switch info is queried during auxiliary probe so that
SF representors are properly identified and vport metadata is initialized.

Patch 3 fixes vport action flag selection for hotplugged representors
to use the proxy port's FDB mode rather than the representor's.

v1: https://mails.dpdk.org/archives/dev/2026-January/330009.html

Changes since v1:
- Attempt to disable ROCE on the SF auxiliary device when hotplugging SF representors
- Fixes for vport metadata querying during hotplug
