Subject:   Gigabit Link slow, until downed and re-uped
Message-ID:  <001601c2edf8$3e008910$0200000a@sewer.org>

My gigabit link between my Windows XP box and my FreeBSD box is always
really slow after booting FreeBSD, until I go like this:

ifconfig em0 down ; ifconfig em0 up

..and then I get top speed again. Ping goes from 9ms+ to 0.2ms-. This
happens regardless of whether the FreeBSD box is booted first, or
second, or even across reboots. However, after fixing it manually, doing
a 'shutdown now' and 'exit' (right away) shows them still working fast.
The only idea I have is that I tried chaning the MAC address on the FBSD
box adapter, but all configuration is back to the way it was. Both cards
are Intel PRO/1000MT adapters. If there is any more info that I should
give, please let me know.
