share/man/man9 : if_rxr_init.9
Log message:
Set timeout(9) to refill the receive ring descriptors if the amount of
descriptors runs below the low watermark.
The em(4) firmware seems not to work properly with just a few descriptors in
the receive ring. Thus, we use the low water mark as an indicator instead of
zero descriptors, which causes deadlocks.
