  Modified files:
    sys/pci              if_rl.c 
  Log:
  Adjust TX threshold on every TX underrun.  Some supported cards (8139-based)
  can retransmit on TX underrun and set TOK in addition to TUND.  Also add a
  check to prevent overflow of the addressable threshold.
  
  This fixes some reports of rl(4) slowness, believed to be related to ALTQ
  before.
