From a1542d6683796d745c5097aff9fa41757a98b367 Mon Sep 17 00:00:00 2001 From: Alexander Duyck Date: Thu, 22 Oct 2015 16:26:42 -0700 Subject: [PATCH] ixgbe: Allow FDB entries access to more RAR filters This change makes it so that we allow the PF to make use of all free RAR entries for FDB use if needed. Previously the code limited us to 16 unicast entries, however this was shared between MACVLAN which wasn't limited and the FDB code which was. So instead of treating the FDB code as a second class citizen I have updated it so that it has access to just as many entries as the MACVLAN filters.
