Bug#522922: regression tests

[dann frazier <dannf@debian.org>]

The igb driver in stable currently supports these device:

#define E1000_DEV_ID_82575EB_COPPER           0x10A7
#define E1000_DEV_ID_82575EB_FIBER_SERDES     0x10A9
#define E1000_DEV_ID_82575GB_QUAD_COPPER      0x10D6

I obtained access to cards containing the first two chips[1] and did
some basic testing (discovery/dhcp/ssh connections). All ports worked
fine using both the current kernel in stable and with Ben's patch.

I don't see any changes in the patch that would affect the 82575GB_COPPER
that don't apply to the 82575EB_COPPER.

I'll have access to these cards for a while, so I can run any
additional tests upon request.

Ben: are you ok with me applying this to stable?


[1] 2 copper cards (single port/dual port), 1 fiber (dual port)
