This patch triggers the RecycleEvent for invalid ARP packets.
Prior to this, we would just ignore invalid ARP packets,
and never free them.

Hi, Nicholas
Should the signal recycle event also be added to below if condition?
if (RxData->DataLength < sizeof (ARP_HEAD)) {
//
// Restart the receiving if packet size is not correct.
//
goto RESTART_RECEIVE;
}
Best Regards
Siyuan

Please put a space character in the subject line, before the
"(CVE-2019-14559)" part.
Please also drop the trailing dot.

Hi Nicholas,
Instead of adding gBS->SignalEvent() lines, please utilize
RECYCLE_RXDATA goto label. You can find the same gBS->SignalEvent()
being done there.
Additionally, please apply goto change in place pointed by Siyuan.
Thanks,
Maciej
