The vring index (MAC queue id) must be set in all TX descriptors
otherwise HW will fail to release descriptors for a specific vring
(disconnect or vring switch flows).
This is normally occurs when fragmentation required, if vring index
will not be the same for all SKB descriptors HW will fail to flush
this MAC queue.

The current code uses the same index value both
for the channel information array and for the TX
power table. The index starts from 14, however the
index of the TX power table must start from zero.

Fix it, in order to get the correct TX power value
for a given channel.

The changes in rt61pci.c and rt73usb.c are compile
tested only.

Most of these relate to endianness problems, and are purely cosmetic.

But a couple of them were legit -- listen interval parsing and some of
the rate selection code would malfunction on BE systems.

There's still one cosmetic warning remaining, in the (admittedly) ugly
code in cw1200_spi.c.  It's there because the hardware needs 16-bit SPI
transfers, but many SPI controllers only operate 8 bits at a time.

If there's a cleaner way of handling this, I'm all ears.

ath_tx_txqaddbuf assumes that all the linked buffers in the queue passed
to it are part of the same A-MPDU or MPDU. The CAB queue rework violates
this assumption, which can cause the internal queue depth to go

This patch modifies the stop_discovery function so it uses the HCI
request framework.

The HCI request is built according to the current discovery state
(inquiry, LE scanning or name resolving) and a complete callback is
register to handle the command complete event for the stop discovery
command. This way, we move all stop_discovery mgmt handling code
spread in hci_event.c to a single place in mgmt.c.

In order to have a better HCI error handling in interleaved discovery
functionality, we should use the HCI request framework.

This patch updates le_scan_disable_work function so it uses the
HCI request framework instead of the hci_send_cmd helper. A complete
callback is registered (le_scan_disable_work_complete function) so we
are able to trigger the inquiry procedure (if we are running the
interleaved discovery) or to stop the discovery procedure (if we are
running LE-only discovery).

This patch also removes the extra logic in hci_cc_le_set_scan_enable
to trigger the inquiry procedure and the mgmt_interleaved_discovery
function since they become useless.
