[-- Attachment #1: tx_control_bitfields.patch --]
[-- Type: text/plain, Size: 26131 bytes --]
All one-bit bitfields have been subsumed into the new 'flags'
structure member and the new IEEE80211_TXCTL_* definitions. The
multiple bit members were converted to u8, s8 or u16 as appropriate.

Both one-bit bitfields have been subsumed into the new 'flags'
structure member and the new IEEE80211_TX_STATUS_* definitions.

[-- Attachment #1: key_conf_bitfields.patch --]
[-- Type: text/plain, Size: 5685 bytes --]
All three one-bit bitfields have been subsumed into the new 'flags'
structure member and the new IEEE80211_KEY_* definitions. The 8 bit
keyidx bitfield is converted to type s8.
