hi Hans

i've seen you made 2 patches for ure driver which looked like a little with the 
problem im having here.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=256675

problem is, its not compiling any longer, code must have changed since you made 
the patch.

regarding the "axge" bugzilla you sent me , THATS EXACTLY the problem im 
having. The workaround for the guy's problem 
was doing this:

# ifconfig ue0 media 1000baseT mediaopt flow

problem is, my ure/ue0 interface does not have that option "flow"

-----------------------------
[tzk@tzk-inspiron ~ ]$ ifconfig -m ue0
ue0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 1500

--------------------------------

any ideas or any other patch you made ?
appreciate any insights

thanks in advance
