Eyal Shapira ee91d18551 wl12xx: mark no sched scan only after FW event
stop sched scan isn't an immediate operation
and we need to wait for PERIODIC_SCAN_COMPLETE_EVENT_ID
after sending a stop before changing internal state
and notifying upper layers.
Not doing this caused problems when canceling an existing sched
scan and immediately requesting to start a new one
with a different configuration as the FW was still
in the middle of the previous sched scan.

Luciano Coelho 0f4e31222a wl12xx: move debugging definitions to a separate file
Separate the debugging macros and other definitions to a new debug.h
file.  This is be needed because the sdio and spi modules don't need
to depend on the wl12xx module anymore, but still need to include
wl12xx.h.  Currently they do depend on it, because of the debugging
global that wl12xx exports.  A future patch will remove this
dependency.

Eliad Peller 1b92f15ee0 wl12xx: add band field to wlvif
add band field into the per-interface data.

mac80211 configures some values (e.g. band, channel)
globally, while we configure them per-interface.

In order to make it easier to keep track of the
configured value for each value while keeping sync
with mac80211, save these values both globally
and per-vif.

Use it instead of wl->mac_addr.

It seems that due to some fw bug, we still need to set nvs->mac

Thus, use wl->mac_addr for this purpose, and don't delete it yet.

In AP mode we register for the MAX_TX_RETRY and INACTIVE_STA events.
Both are reported to the upper layers as a TX failure in the offending
stations.

In STA mode we register only for the MAX_TX_RETRY event. A TX failure is
interpreted as a loss of connection.

Support for IEEE80211_HW_REPORTS_TX_ACK_STATUS has been removed to avoid
the inherent race condition of a mac80211 TX failure counter in addition
to the FW counter.

This patch depends on "mac80211: allow low level driver to report packet
loss"

Eliad Peller c1b193eb65 wl12xx: rearrange some ELP wake_up/sleep calls
ELP (Extremely/Enhanced Low Power, or something like that ;)) refers to
the powerstate of the 12xx chip, in which very low power is consumed,
and no commands (from the host) can be issued until the chip is woken up.

Wakeup/sleep commands must be protected by a wl->mutex, so it's generally
a good idea to call wakeup/sleep along with the mutex lock/unlock (where
needed). However, in some places the wl12xx driver calls wakeup/sleep in
some "inner" functions. This result in some "nested" wakeup/sleep calls
which might end up letting the chip go to sleep prematurely (e.g. during
event handling).

Fix it by rearranging the elp calls to come along with mutex_lock/unlock.
