Kernel: Make sure we read all packets

Browse source 
The previous patch already helped with this, however my idea of only
reading a few packets didn't work and we'd still sometimes end up not
receiving any more packets from the E1000 interface.

With this patch applied my NIC seems to receive packets just fine, at
least for now.
