New Revision: 280825
URL: https://svnweb.freebsd.org/changeset/base/280825
Log:
Fix more ticks wrapping bugs exposed by the ticks wrapping bug check.
This symptom is "calibrations don't ever run", which may cause some
pretty spectacularly bad behaviour in noisy environments or with longer
uptimes.
Thanks to dtrace to make it easy to check if specific non-inlined functions
are getting called by things like the ANI and calibration HAL methods.
Grr.
Tested:
* AR9380, STA mode
