Excellent! Thank you for verifying this.

I'll ask re@ (by assigning the PR to re@) if they can merge the two patches
from stable/13 into releng/13.1, and publish an errata. This patch didn't quite
make it into releng/13.1.

The two patches fix a multitude of problems in wpa_supplicant and hostapd
because a legitimate zero bytes returned can be confused with an error
resulting in zero bytes returned. pcap_next_ex() solves this for us by
returning the return code separately from the bytes returned whereas
pcap_next() results in a confusing result.

The other alternative would be to use the security/wpa_supplicant port. It
includes the patch.

BTW, you should only need to do a git apply against the patch. Then cd
/usr/src/usr.sbin/wpa. Then make obj; make depend; make includes; make; make
install.

re@, would it be possible to publish an errata for this?
