Two things I notice there -- there's a bit of flow control traffic from
your switch (not sure if that's an issue here), and it looks like you
have TCP segmentation offloading enabled.

It may not apply to your hardware, but I've had terrible results with
e1000g's TCP offload.  It seems to trash packets on some devices,
including the Intel PRO/1000 dual-port card in my system at home.

The fix to disable hardware pessimization is to add these two lines to
/kernel/drv/e1000g.conf:

tx_hcksum_enable=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0;
lso_enable=0,0,0,0,0,0,0,0,0,0,0,0,0,0,0,0;

Perhaps it doesn't apply to you, but it's at least worth a try.
