Hey Ben, could you explain more on this 'incremental'?
I think with this commit, the bfd does control the forwarding of group
action
in the following way:
1. when bfd forwarding flag flaps, it changes the global sequence number.
2. as reaction to global sequence number change, port_run() is executed.
3. if the port_run() execution finds that the 'ofport->may_enable' flaps and
sets the 'backer->need_revalidate'.
4. the set of 'backer->need_revalidate' causes the dp flow revalidation and
changes the forwarding of group action.
Does this make sense?
Thanks,
Alex Wang,
