  Modified files:
    sys/dev/netif/et     if_et.c 
  Log:
  - Recollect TX descs, if et(4) is going to enter OACTIVE state.
  - Add additional parameter to et_txeof(), so that calling et_txeof() in
    et_start() will not create recursion.
  - Increase TX segments per interrupt to 256 after above changes.
  
  This gives me additional +10Kpps 64bytes packet TX performance improvement
  (now 918Kpps) and interrupt rate reduction.
