Subject: [net-next 04/15] net/mlx5: Update vport caps query/set for EC VFs

From: Saeed Mahameed <[email-masked]>
Date: Fri, 9 Jun 2023 18:42:43 -0700

From: Daniel Jurgens <[email-masked]>

These functions are for query/set by vport, there was an underlying
assumption that vport was equal to function ID. That's not the case for
EC VF functions. Set the ec_vf_function bit accordingly.
