It seems that people just keep on adding stuff to __skb_clone

The scratch pad register is used to store firmware status after
firmware is downloaded and initialized. After firmware status is
verified OK, the same register is used to store RX packet length.
Hence the firmware status code is no longer valid afterwards.

which will never be overwritten.

Some APs seem to drift away from the expected TBTT (timestamp %
beacon_int_in_usec differs quite a bit from zero) which can result in
us waking up way too early to receive a Beacon frame. In order to work
around this, re-configure the Beacon timers after having received a
Beacon frame from the AP (i.e., when we know the offset between the
expected TBTT and the actual time the AP is sending out the Beacon
frame).

The previous version used a simple loop to go through all Beacon
frames when determining the next TBTT and DTIM count. This is not too
bad for the case where the setup happens before timesync (i.e., very
small TSF), but this can become very heavy operation if a short Beacon
interval is used and the current TSF is large.

In preparation for a patch to update timer setup based on Beacon
timestamp, optimize this routine to take fixed time regardless of the
actual TSF value.

Usually, the 16-bit rx length is read from scratch pad registers
with two CMD52 transactions:
SD8385: 	IF_SDIO_SCRATCH_OLD (0x80fe/0x80ff)
SD8686/SD8688:	IF_SDIO_SCRATCH     (0x34/0x35)

Alternatively, SD8688 firmware offers an enhanced method for driver
to read an 8-bit rx length (in units) with a single CMD52:
IF_SDIO_RX_UNIT 0x43 is read one time after firmware is ready.
IF_SDIO_RX_LEN  0x42 is read every time when rx interrupt is received.
