Hi Thomas,

I put already some comment into other fix patch [1].

Mainly taking into account of current time for release, this patch make
sense, but I suggest giving a chance to the fix mentioned above.

Because the original patch is for safer igb_uio, and fixing a few times
reported issue.

Since this is rc1, we have time for testing, and many parties will be
doing tests. Lets get the fix for rc1, and if we find any issue revert
the patch?

Thanks,
ferruh
