Bug#627700: New Intel Ethernet adapters (e1000e driver)
Hi,
> In this kernel version, the e1000e driver is missing support for
> i82567V-4 and i82579 and important bug fixes for i82577, i82578 and
> i82583.
Here's our test results for the previously unsupported 82579V card:
lspci -vv:
00:19.0 Ethernet controller: Intel Corporation Device 1503 (rev 05)
Subsystem: Intel Corporation Device 2002
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 27
Region 0: Memory at fe700000 (32-bit, non-prefetchable) [size=128K]
Region 1: Memory at fe728000 (32-bit, non-prefetchable) [size=4K]
Region 2: I/O ports at f040 [size=32]
Capabilities: [c8] Power Management version 2
Flags: PMEClk- DSI+ D1- D2- AuxCurrent=0mA
PME(D0+,D1-,D2-,D3hot+,D3cold+)
Status: D0 PME-Enable- DSel=0 DScale=1 PME-

Kernel driver in use: e1000e
Kernel modules: e1000e
lspci -n
00:19.0 0200: 8086:1503 (rev 05)
> 1. If the driver tries to load firmware (only required for some chips),
> does this work once the firmware file(s) are installed?
No firmware is being loaded.
> 2. Can you receive and transmit VLAN-tagged frames after creating a VLAN
> interface?
The tests outlined in #627704 were successful.
> 3. Does the interface work after suspend and resume?
I couldn't test this; suspend doesn't work properly on that system.
> 4. Does the interface work after removing the cable for 10 seconds and
reinserting it?
That worked fine.
> 5. Does multicast configuration work? (IPv6 autoconfiguration or mDNS will
cover this.)
"avahi-browse --all" worked fine.
> 6. Can the interface send and receive TCP/IP across a LAN at the same
speed, before and after these changes? (Use e.g. netperf to test this, but
don't forget to remove the netperf package after use.)
Since the card was previously unsupported I cannot compare it to the previous
state. The performance of large file copies was quite ok.

tests?
None.
