2e42c203a9 wlcore: use psd_type indexing according to spec
In ieee80211.h the uapsd bit mask is defined such that
VO=BIT(0), VI=BIT(1), BK=BIT(2), BE=BIT(3).
The firmware uses the indexing as defined in the ieee80211
spec, meaning that VO=3, VI=2, BK=1, BE=0.

In AP mode when adding peer wlcore needs to convert
the indexing accordingly.

6b8bf5bc5e wlcore: fixes for connection_loss_work
We can't use cancel_delayed_work_sync() from functions that take the
wl->mutex, since connection_loss_work also takes the mutex. This might
result in a deadlock. Restructure the code so the work is synchronously
canceled before taking the mutex.
Avoid a bug where we would indefinitely delay the connection loss
indication by re-queuing the connection loss work on consecutive beacon
loss events.

b5d6d9b28c wlcore/wl12xx/wl18xx: don't use TX align quirk for wl127x
Commit 4afc37 (wlcore: reorder identify_chip and get_hw_info) broke
support for wl127x chips.

When we moved the identify_chip operation to an earlier stage (ie. to
the probe function), we broke wl127x support because during HW init we
would set the WLCORE_QUIRK_TX_BLOCKSIZE_ALIGN.

To avoid this, set this quirk in the identify_chip operations and only
force it to be unset if the bus module doesn't support it.  We were
doing the opposite and setting the flag if the bus module supports it.

d5b592764f wl18xx: translate and write the board type to SCR_PAD2
The firmware uses the SCR_PAD2 register to read the board type passed
from the driver.  The values don't match the ones used in the mac and
phy configuration, so we need to map them before writing.  This commit
adds a translation table that is used when writing the board type to

Different board types (ie. FPGA, HDK and DVP/EVB) require slightly
different init configuration options.  Since we cannot probe the type

This patch adds a module parameters that accepts the 3 different board
types, with DVP/EVB as the default, and uses this value where needed.
