Provide MS() and SM() macros for 80211 and wireless drivers.

2020-09-24T10:57:39Z

We have (two versions) of MS() and SM() macros which we use throughout the wireless code. Change all but three places (ath_hal, rtwn, and rsu) to the newly provided _IEEE80211_MASKSHIFT() and _IEEE80211_SHIFTMASK() macros. Also change one internal case using both _S and _M instead of just _S away from _M (one of the reasons rtwn and rsu were not changed). This was done semi-mechanically. No functional changes intended.

WiFi: fix ieee80211_media_change() callers

2020-09-07T15:35:40Z

In r178354 with the introduction of multi-bss ("vap") support factoring out started and with r193340 ieee80211_media_change() no longer returned ENETRESET but only 0 or error. As ieee80211(9) tells the ieee80211_media_change() function should not be called directly but is registered with ieee80211_vap_attach() instead. Some drivers have not been fully converted. After fixing the return checking some of these functions were simply wrappers between ieee80211_vap_attach() and ieee80211_media_change(), so remove the extra function, where possible as well.

[iwn] Set default ampdu parameters.

These are from the linux iwlwifi driver ;the default use smaller maximum AMPDUs (8k) and a much smaller density (none.) The latter could cause stability issues. Tested: * Tested on Intel 6300, STA mode. Differential Revision: https://reviews.freebsd.org/D25113

Widen EPOCH(9) usage in PCI WLAN drivers.

2020-01-30T10:28:01Z

Make sure all occurrences of ieee80211_input_xxx() in sys/dev are covered by a network epoch section. Do not depend on the interrupt handler nor any taskqueues being in a network epoch section. This patch should unbreak the PCI WLAN drivers after r357004. Pointy hat: glebius@ Sponsored by: Mellanox Technologies

Fix ieee80211_radiotap(9) usage in wireless drivers:

2019-03-11T01:27:01Z

- 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. Tested with Netgear WG111 v3 (urtw(4)), STA mode. MFC after: 2 weeks

iwn(4): plug initialization path vs interrupt handler races

2019-02-06T01:34:14Z

There are few places in interrupt handler where the driver lock is dropped; ensure that device is still running before processing remaining ring entries. PR: 192641 MFC after: 5 days

iwn(4): (partially) rewrite A-MPDU Tx path

2019-01-16T12:33:06Z

Generic Tx stats fixes: - do not try to parse "aggregation status" for single frames; send them to iwn_tx_done() instead; - try to attach mbuf / node reference pair to reported BA events; allows to fix reported status for ieee80211_tx_complete() and ifnet counters (previously all A-MPDU frames were counted as failed - see PR 210211); requires few more firmware bug workarounds; - preserve short / long retry counters for wlan_amrr(4) (disabled for now - causes significant performance degradation). - Add new IWN_DEBUG_AMPDU debug category. - Add one more check into iwn_tx_data() to prevent aggregation ring overflow. - Workaround 'seqno % 256' != 'current Tx slot' case (until D9195 is not in the tree). - Improve watchdog timer updates (previously watchdog check was omitted when at least one frame was transmitted). - Stop Tx when memory leak in currently used ring was detected (unlikely to happen). - Few other minor fixes. Was previously tested with: - Intel 6205, STA mode (Tx aggregation behaves much better now). - Intel 4965AGN, STA mode (still unstable).
