From cb41c997d4446b39dd03b8a74196125739d7c3ac Mon Sep 17 00:00:00 2001 From: Xin Long Date: Wed, 30 Mar 2016 10:58:39 +0800 Subject: [PATCH] team: team should sync the port's uc/mc addrs when add a port There is an issue when we use mavtap over team: When we replug nic links from team0, the real nics's mc list will not include the maddr for macvtap any more. then we can't receive pkts to macvtap device, as they are filterred by mc list of nic. In Bonding Driver, it syncs the uc/mc addrs in bond_enslave(). We will fix this issue on team by adding the port's uc/mc addrs sync in team_port_add. Signed-off-by: Xin Long Signed-off-by: David S.
