Hey, I have reviewed all of them.

The following drivers were not broken, and your change does 100%
recursive epoch_enter:

bwi, ipw, iwi, iwm, iwn, ral, rtwn, wi, wpi

The following drivers use taskq and would be fixed by D23408:

bwn, malo, mwl, wtap

P.S. A funny note about wtap. You modified even a function that
is a dead code - wtap_rx_deliver(). Gives some clue on quality
of your sweep over all drivers.
