[Bug 260907] if_iwm: i7260 dropping connections silently, module load results in ping > 5000 ms

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=260907 --- Comment #1 from O. Hartmann <ohartmann@walstatt.org> --- I observed a strange behaviour with this WiFi NIC and 13/STABLE and do a followup on my initial PR: when the signal strength of the 2,4 GHz access point is around 55% and below and if the channel is populated, FreeBSD's if_iwm (Intel WiFi i7260, see above) starts showing up really weird ping latencies, see below. In the same spot, same AP, same network, same time I tried to run on the very same notebook Xubuntu 21.10 from an USB flash drive on the very same hardware gives a complete unspectacular picture with approx 20 - 25 ms ping latency to the same remote host - which let me conclude that the issue is with FreeBSD and its if_iwm driver on that hardware. FreeBSD 12.3 and FreeBSD 13.0-p6 doesn't work either, the connection drops are even worse. The funny part on the 10k ms ping latencies is that the subsequent answer is delayed by approx 1 to 2 sec, but not > 10 secs as the value of time=14349.755 ms might suggest - or I'm confused in what is measured here.
