2.6.39: kernel igb and e1000e-1.3.17 driver broken?

[Justin Piszcz <jpiszcz@lucidpixels.com>]

Hello,

I recently bought a 4-port Intel NIC (82580)

03:00.0 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
03:00.1 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
03:00.2 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)
03:00.3 Ethernet controller: Intel Corporation 82580 Gigabit Network Connection (rev 01)

Model name: Intel I340 Server Adapter

Which uses this driver:
  | |    <M>   Intel(R) 82575/82576 PCI-Express Gigabit Ethernet support  | |
  | |    [ ]     Direct Cache Access (DCA) Support                        | |

I have tried with and without the DCA support.

Out of the four ports in the back, only two work, why is this?

[ CARD ]
1 2 3 4
   X X

Where X = working.

I've tried the built-in kernel driver from 2.6.39 as well as the latest
e1000e driver from sf.net (1.3.17), any thoughts?

eth0: negotiated 1000baseT-FD flow-control, link ok <- onboard
eth1: negotiated 100baseTx-FD, link ok              <- middle port 1
eth2: negotiated 1000baseT-FD flow-control, link ok <- middle port 2
eth3: no link                                       <- left most port (plugged in)
eth4: no link                                       <- right most port (plugged in)

The last two parts of each mac addr:

eth1      Link encap:Ethernet  HWaddr XX:XX:XX:XX:3b:f9  WORKING
eth2      Link encap:Ethernet  HWaddr XX:XX:XX:XX:3b:fa  WORKING
eth3      Link encap:Ethernet  HWaddr XX:XX:XX:XX:3b:f8  no link
eth4      Link encap:Ethernet  HWaddr XX:XX:XX:XX:3b:fb  no link

Thoughts?

Justin.
