macvlan: Only deliver one copy of the frame to the macvlan interface
BugLink: http://bugs.launchpad.net/bugs/1745052 [ Upstream commit dd6b9c2c ] This patch intoduces a slight adjustment for macvlan to address the fact that in source mode I was seeing two copies of any packet addressed to the macvlan interface being delivered where there should have been only one. The issue appears to be that one copy was delivered based on the source MAC address and then the second copy was being delivered based on the destination MAC address. To fix it I am just treating a unicast address match as though it is not a match since source based macvlan isn't supposed to be matching based on the destination MAC anyway.
