2019-03-28T09:50:25Z

Fix ieee80211_radiotap(9) usage in wireless drivers: - Alignment issues: * Add missing __packed attributes + padding across all drivers; in most places there was an assumption that padding will be always minimally suitable; in few places - e.g., in urtw(4) / rtwn(4) - padding was just missing. * Add __aligned(8) attribute for all Rx radiotap headers since they can contain 64-bit TSF timestamp; it cannot appear in Tx radiotap headers, so just drop the attribute here. Refresh ieee80211_radiotap(9) man page accordingly. - Since net80211 automatically updates channel frequency / flags in ieee80211_radiotap_chan_change() drop duplicate setup for these fields in drivers.

MFC r343474:

2019-02-10T21:00:02Z

Remove 2GHz channel list copies from wireless drivers. Wrap ieee80211_add_channel_list_2ghz into another function which supplies default (1-14) channel list to it and drop its copies from drivers.

rtwn: fix Tx processing, add some busdma synchronization.

2016-06-20T22:45:19Z

1) Unload mbuf instead of descriptor in rtwn_tx_done(). 2) Add more synchronization for device visible mappings before touching the memory. 3) Improve watchdog timer logic. Reported and tested by: mva Approved by: re (gjb)

rtwn, urtwn: drop unused structures.

2016-05-26T22:43:02Z

urtwn(4) uses another implementation of command queue; rtwn(4) don't need it at all.

urtwn, rtwn, rsu: switch to ieee80211_add_channel_list_2ghz().

2016-05-26T16:39:11Z

- Use device's channel list instead of default one (from ieee80211_init_channels()); adds 12 - 14 2GHz channels. - Add ic_getradiocaps() method.

rtwn: replace hardcoded rate indices with their names (similar to r289758).

2016-05-26T14:17:57Z

- Use macros to define rate indices; don't hardcode them in code. - Add method for 'rate' -> 'rate index' conversion (and array for the opposite). - Determine if rate is CCK / OFDM via appropriate macro. Reviewed by: adrian Differential Revision: https://reviews.freebsd.org/D4837

rtwn: fix double free in raw xmit path.

net80211 + drivers: hide size of 'bands' array behind a macro.

2016-04-29T22:14:11Z

Auto-replace 'howmany(IEEE80211_MODE_MAX, 8)' with 'IEEE80211_MODE_BYTES'. No functional changes.

net80211: replace internal LE_READ_/LE_WRITE_ macro with system

2016-04-20T18:29:30Z

le*dec / le*enc functions. Replace net80211 specific macros with system-wide bytestream encoding/decoding functions: - LE_READ_2 -> le16dec - LE_READ_4 -> le32dec - LE_WRITE_2 -> le16enc - LE_WRITE_4 -> le32enc + drop ieee80211_input.h include, where it was included for these operations only.
