The kernel calls this device ID "MT26438 ConnectX EN 40GigE PCIe gen2 5GT/s". Maybe we should just delete these comments, since we can't seem to get them right?

Are we missing a kernel patch? I don't see this device ID in the kernel driver.

I guess it would be best if we take the description from
http://pciids.sourceforge.net/v2.2/pci.ids

Looks like it is missing.
If we agree on this, we'll send two patches - one for kernel and one for libmlx4 to sync all device IDs with descriptions from the mentioned url.

http://pciids.sourceforge.net/v2.2/pci.ids
I wonder whether it's really worth having the text at all. Maybe it's a bit useful, I'm not sure. But the pciids text could probably use some cleaning up, eg:
634a MT25418 [ConnectX VPI PCIe 2.0 2.5GT/s - IB DDR / 10GigE] 6368 MT25448 [ConnectX EN 10GigE, PCIe 2.0 2.5GT/s]
it would be nice to decide on a standard order of whether the PCIe or the network info comes first.
And then to make things even better we have:
103c 3313 HP NC542m Dual Port Flex-10 10GbE BLc Adapter
so we can't even decide on 10GigE vs. 10GbE.
But yeah, patches to get the ID list into shape with at least the right list of device IDs for kernel and userspace would be welcome.

OK, we'll have them sent next week.
