f5755fe96c wl18xx: PG2.0 HW Watch dog interrupt support
In PG2, the HW watchdog interrupt occupies bit0 of the event vector, and
the SW watchdog is relocated to bit9. We perform the relocation
globally, as there's only one watchdog bit on previous platforms (bit0).

[Only mask in the new bit9 for platforms supporting it. This avoids
spurious events on other platforms - Arik]

6639611467 wlcore: add stop reason bitmap for waking/starting queues
Allow the driver to wake/stop the queues for multiple reasons. A queue
is started when no stop-reasons exist.

Convert all wake/stop queue calls to use the new API.

Before, a stopped queue was almost synonymous a high-watermark on Tx.
Remove a bit of code in wl12xx_tx_reset() that relied on it.

Internal packets arriving from mac80211 are also discarded when a queue
is stopped. A notable exception to this is the watermark reason, which
is a "soft"-stop reason. We allow traffic to gradually come to a halt,
but we don't mind spurious packets here and there. This is merely a flow
regulation mechanism.

a4203c6453 wlcore: wait for roc complete only for the first roc command
In some multi role scenarios the driver might send multi
roc requests without sending a croc first, the fw queues
those requests and starts service the next roc request as
soon as the driver sends a croc for the previous one. So,
if the fw rocs on channel X and driver asks to roc also
on channel Y, the fw will not start service Y (and will
not send roc complete event for this request) until the
driver releases the fw with croc X.

When we moved the identify_chip operation to an earlier stage (ie. to

would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN.

To avoid this, set this quirk in the identify_chip operations and only

7140df6e51 wlcore: create private static_data area and add operation to parse it
The wl18xx firmware has more information in the static_data than
wl12xx.  To be able to parse that in an abstracted way, this patch
adds a priv area to the static data struct and an operation that
allows the lower driver to parse it if necessary.
