Subject: selftests: forwarding: bridge_mdb_max: Fix failing test with old libnet
From: Ido Schimmel <idosch@xxxxxxxxxx>
commit cb034948ac292da82cc0e6bc1340f81be36e117d upstream.
As explained in commit 8bcfb4ae4d97 ("selftests: forwarding: Fix failing
tests with old libnet"), old versions of libnet (used by mausezahn) do
not use the "SO_BINDTODEVICE" socket option. For IP unicast packets,
this can be solved by prefixing mausezahn invocations with "ip vrf
exec". However, IP multicast packets do not perform routing and simply
egress the bound device, which does not exist in this case.
Fix by specifying the source and destination MAC of the packet which
will cause mausezahn to use a packet socket instead of an IP socket.
