Subject: [PATCH 4.9 24/59] net: vrf: Add missing Rx counters

4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: David Ahern <dsa@...ulusnetworks.com>


[ Upstream commit 926d93a33e59b2729afdbad357233c17184de9d2 ]

The move from rx-handler to L3 receive handler inadvertantly dropped the
rx counters. Restore them.

Fixes: 74b20582ac38 ("net: l3mdev: Add hook in ip and ipv6")
