wifi: mac80211: tx: simplify control port frame transmission

Browse source

ieee80211_tx_control_port() already does most of the necessary work,
much of which is repeated by __ieee80211_subif_start_xmit(). Most
work in the latter function is completely unnecessary since these
are special frames we built directly here (long enough, etc.)

Call ieee80211_build_hdr() and ieee80211_xmit() directly instead.

It also means some errors can now be reported to userspace rather
than frames silently getting dropped, but that's a good thing.
