[PATCH net-next 0/2] liquidio: add support for ndo_get_stats64

[Felix Manlunas]

From: Pradeep Nalla <pradeep.nalla@cavium.com>

Support ndo_get_stats64 instead of ndo_get_stats.  Also add stats for
multicast and broadcast packets.

Pradeep Nalla (2):
  liquidio: move a couple of functions to lio_core.c

[PATCH net-next 1/2] liquidio: move a couple of functions to lio_core.c

[Felix Manlunas]

From: Pradeep Nalla <pradeep.nalla@cavium.com>

To support the next patch in this series which has code that calls
octnet_get_link_stats from two different .c files, move that function (and
its dependency octnet_nic_stats_callback) to lio_core.c.  Remove
octnet_get_link_stats's static declaration and add its function prototype
in octeon_network.h.
