[PATCH mlx5-next 2/2] net/mlx5: Add vhca_id_type bit to alias context

From: Tariq Toukan

Date: Thu Mar 19 2026 - 08:24:26 EST


From: Patrisious Haddad <phaddad@xxxxxxxxxx>

Add vhca_id_type bit to alias context which allows indicating the
vhca_id_type to be passed at vhca_id_to_be_accessed, which can be either
HW or SW, note that SW_VHCA_ID must be used to allow alias to work
properly after migration.
