Subject: [PATCH AUTOSEL 4.19 20/56] ixgbevf: Remove limit of 10 entries for unicast filter list

From: Radoslaw Tyl <radoslawx.tyl@...el.com>

[ Upstream commit aa604651d523b1493988d0bf6710339f3ee60272 ]

Currently, though the FDB entry is added to VF, it does not appear in
RAR filters. VF driver only allows to add 10 entries. Attempting to add
another causes an error. This patch removes limitation and allows use of
all free RAR entries for the FDB if needed.

Fixes: 46ec20ff7d ("ixgbevf: Add macvlan support in the set rx mode op")
