Hi Pravin
one question about openvswitch, why we add BUILD_BUG_ON in flow_hash?
It is never be true, right ?
flow_hash
...
/* Make sure number of hash bytes are multiple of u32. */
BUILD_BUG_ON(sizeof(long) % sizeof(u32));
...

One question, why now ovs can only set the mac of internal interface,
for example:
ovs-vsctl set Interface p1 type=internal mac=\"00:11:22:33:44:55\"
ovs-vsctl get Interface p1 mac_in_use
And the doc about 'mac' is not explained, why we cannot set it for
other type interface. So it's a bug?
