32 bit alignment of this struct, but it may confuse someone else in the
future, I agree. I'll change it to u8.

I agree. Good point and thanks for the catch.
Would appreciate your opinion for next possible solution:
I'll Move ieee80211_rx_h_data_agg before ieee80211_rx_h_802_1x_pae, and
assuming I identify A-MSDU, I'll loop for each internal MSDU on:
ieee80211_rx_h_802_1x_pae
ieee80211_rx_h_drop_unencrypted
ieee80211_rx_h_data
return value of ieee80211_rx_h_data_agg to
__ieee80211_invoke_rx_handlers will be this small loop's return value
