I just tried the brand-new v3.11, and the usual, trivial:

# echo -n 8 > /sys/bus/pci/devices/0000:04:00.0/sriov_numvfs

was enough to blow up my box the same old boring way (infinite string
of "ixgbevf 0000:04:11.0: Last Request of type 03 to PF Nacked"
messages.

I guess this is because v3.11 still includes the 2.7.12-k ixgbevf
driver, not the apparently-fixed 2.10.3 version from your sourceforge
page.

According to sourceforge, 2.7.12 was released almost a YEAR ago, on
2012-10-18, and 2.10.3 was released 2013-07-26. Why isn't 2.10.3 in
v3.11?

Don't you guys care that it is so easy to blow up your driver with the
mainline kernel? I'm quite frustrated by how much time I've wasted on
this issue.

I do not think that defending yourself with "please try the latest
driver from sourceforge" is a reasonable or friendly way to work in
the Linux community.
