v2 is out. I do not have a txgbe NIC, so it is compile-tested
only.
Would you be able to test it on a txgbe NIC?

With the port started: create and delete one FDIR rule ten
times, then check that PBRXSIZE(0) (0x19020) does not keep
shrinking and that FDIRCTL (0x19500) is 0 after delete.
flow validate must not change either register. A rule with an
out-of-range queue must fail and leave them unchanged. flow
flush must restore PBRXSIZE(0). SP and AML if you have both.
