In the special case hardware scan fails to start, we cancel the scan with net80211 and cleanup our part. In that case we now sleep and wait for a wakeup. The wakeup was moved to a different callback function to serve both cases (hw scan cancelled, and hw scan failed). In the very special case the hardware scan fails with a return code of 1, we need to start a software scan. I cannot fully imagine this ever worked well (some rtw88 chipsets are using this). The trouble is that the cancael_scan runs in a taskq in net80211 and by the time we tried to start the new scan, the old one was not fully cleaned up and finished (or could have been restarted in case we enable bgscan). So defer starting the software scan to the taskq as well and it will run once the previous finished. The RTW8821ce I tested with seemed a lot more happy.

FreeBSD Source:
This is the top level of the FreeBSD source directory.
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
