fresh em(4) patch for RELENG_6 available

[Gleb Smirnoff]

  Colleagues,

  although one week ago we have made a very big merge of the
em(4) driver from HEAD to RELENG_6, during this week the driver
has experienced few important changes in HEAD:

  1) Pyun YongHyeon has fixed problems in both TX and RX path
     that can happen when system experiences mbuf shortage.
  2) Intel's driver version 6.1.4 has been merged.

The patch for RELENG_6 is available here:

http://people.freebsd.org/~glebius/em-RELENG_6.patch

Currently there is also a known problem - a race condition,
that occurs on SMP triggering a fake watchdog event, that
leads to unwanted NIC reset.
