This patch fails to compile because there is a call to
ixgbevf_write_tail() which you missed cleaning up.

For a change with delicate side effects, it doesn't create much
confidence if the code does not even compile.

Sinan, please put more care into the changes you are making.

I think the issue is the tree that code is getting tested has undelivered code as Alex mentioned.

I was using linux-next 4.16 rc4 for testing.

I will rebase to Jeff's tree.


Thank you.
