ipfw "unknown interface name igb1" SOLVED

[Graham Menhennitt]

Thanks for replying, Sergey.

The "igb" device is no longer available as an option in the kernel 
source - I need to use "em" instead. Without "em" most things still 
work, though - just not the ipfw rules on boot. Strangely, my interfaces 
still come up as "igb".

Anyway, with "em" it all now works. Thanks!
