**Minor style concern:** The nl80211.h kdoc comment is at line 3188 but is
missing `@` cross-references to the commands that actually use it
(`NL80211_CMD_FRAME`). Standard nl80211 practice is to reference the specific
command and operation (TX vs RX) more explicitly.

**NL80211_ATTR_FRAME_CMD_NO_STA name:** The "CMD" in the middle is awkward.
It implies this is only relevant to `NL80211_CMD_FRAME`, which is true, but
the naming convention for other per-command attributes (e.g.
`NL80211_ATTR_FRAME`, `NL80211_ATTR_FRAME_MATCH`) omit "CMD". Consider
`NL80211_ATTR_FRAME_NO_STA` for consistency.
