Subject: [dpdk-dev] [PATCH] net/bonding: add ethdev ops function for MTU set
Date: Thu, 11 Jan 2018 11:12:44 -0800 [thread overview]
Message-ID: <20180111191244.28520-1-sharmila.podury@gmail.com> (raw)
From: Sharmila Podury <sharmila.podury@att.com>
Set the MTU for bonding device by calling .mtu_set for all
the slaves. Set the MTU only if all slaves support .mtu_set,
and there is no error returned from any slave.
