Gleb Smirnoff 66e58c20dd From the PR: 
The receive function em_process_receive_interrupts() unlocks the
  adapter while ether_input() processes the packet, and then locks
  it back. In the meantime, em_init() may be called, either from
  em_watchdog() from softclock interrupt or from the ifconfig(8)
  program. The em_init() resets the card, in particular it sets
  adapter->next_rx_desc_to_check to 0 and resets hardware RX Head
  and Tail descriptor pointers. The loop in
  em_process_receive_interrupts() does not expect these things to
  change, and a mess may result.

This fixes long wedges of em(4) interfaces receive part under high
load and IP fastforwarding enabled.
