[Etherlab-users] Dual Ethernet Box and kernel driver configuration

[Mike O'Connor]

Hi Andreas

Thanks for your reply.

I was having issues with the interface (ec_igb driver) for normal 
Ethernet not always starting up and working, but I switched to a newer 
kernel and this issue went away.

I think it would be best if the driver was loaded but only bound to the 
active interface.

I'm having another issue which I'll send with a new subject.


Again thanks

Mike
