From: Gleb Smirnoff <gleb...@freebsd.org> due to peer pressure switch over to opt-in instead of opt-out for epoch.
Instead of IFF_NEEDSEPOCH, provide IFF_KNOWSEPOCH. If driver marks itself with IFF_KNOWSEPOCH, then ether_input() would not enter epoch when processing its packets. Now this will create recursive entrance in epoch in >90% network drivers, but will guarantee safeness of the transition. Mark several tested drivers as IFF_KNOWSEPOCH.
