Some masks for the destination MAC are supported. Heres the description from
the ovs-ofctl man page:
dl_dst=xx:xx:xx:xx:xx:xx/xx:xx:xx:xx:xx:xx
Matches an Ethernet destination address specified as 6 pairs of
hexadecimal digits delimited by colons (e.g. 00:0A:E4:25:6B:B0),
with a wildcard mask following the slash. Only the following
masks are allowed:
01:00:00:00:00:00
Match only the multicast bit. Thus,
dl_dst=01:00:00:00:00:00/01:00:00:00:00:00 matches all
multicast (including broadcast) Ethernet packets, and
dl_dst=00:00:00:00:00:00/01:00:00:00:00:00 matches all
unicast Ethernet packets.
fe:ff:ff:ff:ff:ff
Match all bits except the multicast bit. This is proba‐
bly not useful.
ff:ff:ff:ff:ff:ff
Exact match (equivalent to omitting the mask).
00:00:00:00:00:00
Wildcard all bits (equivalent to dl_dst=*.)
You can also do it through a controller if your controller supports NXM.
That's defined in "include/openflow/nicira-ext.h" with the NXM_OF_ETH_DST_W
match.
