Subject: [PATCH net-next 2/2] qed: Fix Config attribute frame format.

MFW associates the entity id to a config attribute instead of assigning
one entity id for all the config attributes.
This patch incorporates driver changes to link entity id to a config id
attribute.

Fixes: 0dabbe1bb3a4 ("qed: Add driver API for flashing the config attributes.")
