Felix Fietkau 06288a8e37 mac80211: ensure that mgmt tx skbs have tailroom for encryption ... commit 9d0f50b80222dc273e67e4e14410fcfa4130a90c upstream. Some drivers use IEEE80211_KEY_FLAG_SW_MGMT_TX to indicate that management frames need to be software encrypted. Since normal data packets are still encrypted by the hardware, crypto_tx_tailroom_needed_cnt gets decremented after key upload to hw. This can lead to passing skbs to ccmp_encrypt_skb, which don't have the necessary tailroom for software encryption. Change the code to add tailroom for encrypted management packets, even if crypto_tx_tailroom_needed_cnt is 0.
