<1569329773-10185-1-git-send-email-arybche...@solarflare.com>
From: Ivan Ilchenko <ivan.ilche...@oktetlabs.ru>
Change rte_eth_allmulticast_enable()/rte_eth_allmulticast_disable()
return value from void to int and return negative errno values
in case of error conditions.
Modify usage of these functions across the ethdev according
to new return type.
