The full looking up on flow table traverses all mask array.
If mask-array is too large, the number of invalid flow-mask
increase, performance will be drop.
One bad case, for example: M means flow-mask is valid and NULL
of flow-mask means deleted.

When creating and inserting flow-mask, if there is no available

It's more straight forward to start with using IPv6 NAT, matching the

Idea is to log lacp specific tx failure. A one step further as in
ofproto_dpif_send_packet has to make the debug info more generic, even
though it would cater all of its calling functions.
For example, bundle_send_learning_packets reports such tx failures for
