  I had a lot of such problems with 7.1.9 on my 82566DM, and I
thought, that new driver is Ok, but yesterday it happens again with
7.2.3.

  No packets could be sent, buffers are overfilled, only full reset
helps (after "ifconfig wm0 down && ifconfig em0 up" ping starts to
report "Host is down" for any remote host, instead of "No buffer space
available")...

  8-STABLE, 7.2.3 driver, amd64, 82566DM LOM chip.
