Dear Jason With a link_irq of 4, I still guess your problem is snd_buf filling up during a temporary link_loss (see: http://lists.freebsd.org/pipermail/freebsd-net/2011-November/030424.html). I use a patched version of e1000 which addresses this issue and works good for me but it is based on 7.2.3 and I have just tested in on 7.3-RELEASE. If interested, I can send you the sources for test. You may also port my changes to 7.3.2 and roll your own version.
