So what you want to do in -RT right now is to use something like the
mac80211_hwsim.c:
https://git.kernel.org/pub/scm/linux/kernel/git/rt/linux-rt-devel.git/commit/?h=linux-4.13.y-rt&id=29158ad20a5363c581110497f430fa98b4280c5c
but I will update that softirq patch I have now in tree with the
version which is staged for upstream and then it will change slightly:
