[PATCH net-next v2 1/6] net: dcb: modify dcb_app_add to take list_head ptr as parameter

From: Daniel Machon
Date: Mon Jan 16 2023 - 10:01:11 EST


In preparation to DCB rewrite. Modify dcb_app_add to take new struct
list_head * as parameter, to make the used list configurable. This is
done to allow reusing the function for adding rewrite entries to the
rewrite table, which is introduced in a later patch.
