sam@ and various open source repositories:
ath(4):
Ignore "phantom" beacon misses: should stabilize connections
to access points (no more ceaseless link-UP/DOWN indications).
Also, re-synchronize beacon timer using the TSF in the
first beacon received after joining a BSS---this should
also help suppress spurious beacon misses. I am hopeful
that this will help ath(4) lossage reported by perry@ and
smb@.
Add new configuration through sysctl.
Use a shorter calibration interval until IQ calibration
finishes.
Report antenna noise through radiotap.
Rudiments of Radar Detection / Dynamic Frequency Selection.
Update to HAL version 0.9.16.13.
Update open sources for changes to the HAL API.
Add HALs for additional architectures: add big-endian ELF
HALs for sparc64 and for PowerPC. Also add a Alpha HAL.
These new HALs are untested under NetBSD.
ath(4) + net80211:
Make the multicast transmit rate configurable by ioctl.
Miscellaneous bug fixes.
