[v2,02/13] net/failsafe: check code of promiscuous mode switch
Checks
Commit Message
From: Ivan Ilchenko <Ivan.Ilchenko@oktetlabs.ru>
rte_eth_promiscuous_enable()/rte_eth_promiscuous_disable() return
value was changed from void to int, so this patch modify usage
of these functions across net/failsafe according to new return type.
Try to keep promiscuous mode consistent across all active
devices in the case of failure.
