In my local network (the laptop is working/getting installed in) I use jumb=
o frames on
several server system including the gateway (also FBSD CURRENT).

After I manually set mtu > 1500 (in my case: mtu 6121) the NIC worked as ex=
pected. My
lab's Dell Latitude E6510 laptop (em0) works without setting explicit jumbo=
 frames. This
is a kind of weird ...

Thanks for your patience.

Oliver
