Log:
  Suppress excessive print in ENA HAL
  
  In FreeBSD, this is normal situation that the Tx ring is being full. In
  that case, the packet is put back into drbr and the next attempt to send
  it is taken after the cleanup.
  
  Too much logs like this can cause system instability and even cause the
  device reset (because keep alive or cleanup could be missed).
  
  To fix that, the log level of this message is changed to debug.
