You don't need to do this. In the rx info (struct ieee80211_txrx_data
rx) we already have the bitrate info available (rx->u.rx.rate), you
might not have access to it but __ieee80211_rx() refuses packets with an
invalid rate or band. Hence, you can leave out *all* the sanity checks
and just do
phy->bands[band]->bitrates[rate_idx]
which doesn't need an inline function.
