mac802154: rx: document ieee802154_rx() context requirement
This patch is similar like d20ef63d32461332958661df73e21c0ca42601b0 ("mac80211: document ieee80211_rx() context requirement"). The netif_receive_skb call requires with softirqs disabled. This patch adds a warning if softirqs are pending while calling ieee802154_rx. Signed-off-by: Alexander Aring <alex.aring@gmail.com> Signed-off-by: Marcel Holtmann <marcel@holtmann.org>
