Hello everybody,

I have an issue with an Intel gigabit controller. This is from a Dell Latitude
E6500, lspci -vv says:

00:19.0 Ethernet controller: Intel Corporation 82567LM Gigabit
Network Connection (rev 03) Subsystem: Dell Device 024f
        Control: I/O+ Mem+ BusMaster+ SpecCycle- MemWINV- VGASnoop- ParErr-
Stepping- SERR+ FastB2B- DisINTx+ Status: Cap+ 66MHz- UDF- FastB2B- ParErr-
DEVSEL=fast >TAbort- <TAbort- <MAbort- >SERR- <PERR- INTx- Latency: 0
        Interrupt: pin A routed to IRQ 44
        Region 0: Memory at f6ae0000 (32-bit, non-prefetchable) [size=128K]
        Region 1: Memory at f6adb000 (32-bit, non-prefetchable) [size=4K]
        Region 2: I/O ports at efe0 [size=32]
        Capabilities: [c8] Power Management version 2
                Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA
PME(D0+,D1-,D2-,D3hot+,D3cold+) Status: D0 NoSoftRst- PME-Enable- DSel=0
DScale=1 PME- Capabilities: [d0] MSI: Enable+ Count=1/1 Maskable- 64bit+
                Address: 00000000fee0300c  Data: 4182
        Capabilities: [e0] PCI Advanced Features
                AFCap: TP+ FLR+
                AFCtrl: FLR-
                AFStatus: TP-
        Kernel driver in use: e1000e
        Kernel modules: e1000e

This is how to reproduce:

* Boot ipxe.lkrn from Grub (so no UNDI involved)
* iPXE gets IP address via DHCP and fetches its config
* Select to boot Linux (kernel version 3.14.1)
* Try to get IP address via DHCP from inside Linux system

DHCP just times out (though mii-tool reports link is ok) and I have to power
off the system to make the network controller work again. No issues booting
the same system from Grub directly or via iPXE from BIOS/UNDI.
