--- Comment #1 from Guido Falsi <madpilot at FreeBSD.org> ---
I reported a similar issue some time ago, this is the relevant thread on
net at FreeBSD.org:

http://lists.freebsd.org/pipermail/freebsd-net/2013-September/036645.html

Some patches were tried at the time but the problem was not solved.

I'm currently working around this with a startup script doing:

start_cmd="ifconfig ${refix_if} tso"

(tso is already on by default, just touching the flag wakes up the adapter).


My machine is a Fujitsu siemens tower Esprimo PH300 E85+.
