[Intel-wired-lan] i40e: Deadly GRE packet

Dear Developers,
I have a setup of a pair of SuperMicro-branded XL710s connected with
passive crossover cable, one (eth4) is using firmware 5.0, the other (eth7)
is using fw 4.33. When I send couple of packets with no payload in GRE over
IP over ETH from eth7 to eth4, the receiving card stops processing further
packets. It seems that 4 empty-GRE packets in succession are enough to kill
the card's receivers (all ports stop working), more if there are other
packets inbetween. Transmit direction is not affected. After reboot, the
card comes back, reloading the driver (or unbind/bind) is not enough to fix
the problem.

Tested on stock Debian kernel, with in-kernel driver and one from DPDK-2.2.
