Hallo  Anton,

Not yet to my knowledge. At least according to the man pages it hasn't been merged yet https://www.freebsd.org/cgi/man.cgi?query=iwm&manpath=FreeBSD+12-current is the first version that mentioned 8265.

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=220229 is open for this already, and mentions that its complicated and depends on a number of other commits.

Yes, I've been using it for almost a year now.  My h/w is slightly different to yours but the chip seems to be the same at least.
