IEEE 802.11 wireless stack improvements and bugfixes:
- - Fixed an automatic Tx rate control issue in iwn(4).
- Fixed a bug where outstanding frames on the iwn(4) aggregation queue
- interfere with roaming to another AP.
+ interfered with roaming to another AP.
- Implemented a workaround for missing Tx completion interrupts
in iwm(4) which could lead
- to failed decisions to roam to other APs.
-
- Reenabled firmware-based Tx retries at lower rates for Re-enabled firmware-based Tx retries at lower rates for iwm(4), reducing packet loss.
-
- Fixed an automatic Tx rate control issue in iwm(4) and iwx(4).
-
- Worked around a race condition in Fixed automatic Tx rate control issues in iwn(4), and iwm(4).
+
- Fixed a race condition in iwm(4) Rx interrupt handling.
-
- Added support for active scan to Added support for active scanning to bwfm(4).
-
- Increased throughput of the ifq pressure drop mechanism for bwfm(4).
+
- Fix bwfm(4) behavior which
+ could trigger the ifq pressure drop mechanism under moderate load.
- Improved error handling for bwfm(4) connection attempts.
- Fixed the ifconfig(8) "media:" line
- for 11n wifi interfaces during and after a background scan.
-
- Fixed an mbuf corruption issue in net80211 hostap mode when overlarge SSIDs are used.
-
- Stopped switching to new APs found during background scans
- with RSSI levels which will also trigger background scans, helping to
- prevent repeated switching in areas where APs are tuned for low

- Increased the net80211 node cache size.

- Reduced stalling with lossy wifi by improving net80211
- handling of the Rx block ack sequence number window and queue.

+ which occurred if a relatively long SSID was configured.

- Avoid repeated repeated switching between APs in areas where APs
+ are tuned for low transmit range.

- Increased the net80211 node cache size to allow more APs to be viewed during scans.
