    - Backout if_wm.c rev.1.574 and print "device timeout (lost interrupt)"
     when all descriptors in a queue are free. When all descripters are free after
     wm_txeof(), it's caused by lost interrupt (though I've never seen it). One
     possibility is chip bug and another possibility is software bug. We should
     reset in any cases. If we don't reset and don't print error message, TX
     processing is done intermittently and user might not noticed the problem.

    - Rename txq_watchdog to txq_sending to make the meaning clear.
