iflib and options RSS is a no go for igbX

[Hans Petter Selasky]

Hi,

I just found a bug where outgoing TCP connections over igb0 doesn't work 
because likely the software computed hash is wrong, so the incoming 
packets get dropped because they are received on the wrong queue.

It is the management port, so I'm just using this hack for now:

dev.igb.0.iflib.override_nrxqs=1
dev.igb.0.iflib.override_ntxqs=1
