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.
