Is not that we support MFP in hardware. We just return -EOPNOTSUPP in rt2x00mac_set_key() when mac80211 will try to set MFP ciphers (since rt2x00crypto_key_to_cipher() will return CIPHER_NONE) and we fallback to software encryption. Please repost patch that enable MFP unconditionally with 'Cc: [email protected]' tag. Stanislaw
