When bind with uio_pci_generic in X710/XL710/XXV710, the result is
failed. uio_pci_generic is not supported by X710/XL710/XXV710.

Hi Jeff,

There is a Linux commit causing the issue, right. Commit done because of the
reasons mentioned in "Description". Do you think does it make sense to note
that Linux commit, and Linux kernel version that has been introduced?

Hi, Ferruh
At beginning, we found this issue in latest kernel version, such as kernel 4.7.9 on fedora24.
But later, we observed that this issue also exist on REL7.3.
So, it may be a little difficult to us to figure out exactly which kernel version
doesn't support. And the root cause is the HW's errata which makes uio_pci_generic
cannot be used on XL710 series NICs.

Thanks
