From 1d4ddc4a5370793a24d37b9bd1e2cb52f42e6d65 Mon Sep 17 00:00:00 2001 From: Shannon Nelson Date: Sat, 9 Oct 2021 11:45:16 -0700 Subject: ionic: move lif mac address functions The routines that add and delete mac addresses from the firmware really should be in the file with the rest of the filter management. This simply moves the functions with no logic changes. Signed-off-by: Shannon Nelson Signed-off-by: David S.
