ath9k: perform ANI cycle in idle state

On idle state case, the station wakes up from network sleep for
beacon reception. Since most of the time, ANI cycle is not syncing
with beacon wakeup, ANI cycle is ignored. Approx 5 mins once, the
calibration is performed. This could affect the connection stability

error rates are too high, ANI is unable to tune its immunity level
as quick enough due to rare execution.

Here the experiment shows that OFDM and CCK levels are at default
even on higher phy error rate.

listenTime=44 OFDM:3 errs=121977/s CCK:2 errs=440818/s ofdm_turn=1

orinoco_usb: clean up some signedness issues

In ezusb_read_ltv() we had a comparison "(bufsize < 0)" which was never
true because bufsize was unsigned.  I looked at the implications of
that.  If we passed a negative number to ezusb_access_ltv() then it
would be used as the size parameter of the memcpy() because that
function uses min_t(int, exp_len, ans_size).

But fortunately when I looked at the callers, bufsize is not controlled
by the user and it's never negative.  So these signedness mistakes have
no impact.

I removed the always false check from ezusb_read_ltv() and I changed the
types in ezusb_access_ltv() and made the variables unsigned.

that can be embedded into any interface type.

+         ps = &sdata->u.mesh.ps;

Some references to the AP's beacon structure are removed where they
were obviously not used.

interface with one client in PS mode.
