to read both RSSI level (7 bits) and
antenna diversity (msb)

Instead of splitting the fw_status into 2 and using some
complex calculations, read the fw status and let each low-level
driver (wl12xx/wl18xx) convert it into a common struct.
This is required for the upcoming fw api changes, which
break the current logic anyway.

Treat Rx error code as a bitmask. This allows sending MIC failures
when other error bit are on.
Align Rx descriptor status mask to the FW definition.
Ease debugging in case FW reports failure to decrypt on packets.
Discard corrupted packets early in Rx path to avoid reporting other
abnormalities with corrupted packets that also have other failure bytes on.
Namely - we don't want to get a MIC failure on a corrupted packet.
This is mandated by the WiFi specification - see
section 11.4.2.4.1 in 802.11-2012.

Propagate some missing return values for Rx-filter related functions.
This and makes sure we always fail the suspend in case of SDIO errors.

Propagate errors from wl1271_read and request for recovery when
appropriate.
Also rename prefixes of wlcore functions which their prototypes had to
be changed.

NET_IP_ALIGN can be overriden on different architectures
and therefore cannot be used in the RX path to account
for the 2 bytes added for alignment (either by the FW
in the case of 18xx or by the host for 12xx).
Instead use an internal define.

The number of RX packet descriptors may vary from chip to chip and
in different firmware versions. Unfortunately, the array that
contains the actual descriptors is in the middle of the fw_status
structure. To manage this, we split the struct into two so we can
calculate the offset of what comes after the array and access the last
elements more easily.
[Changed the STATUS_LEN macro to be placement agnostic - Arik]

Add room for a private data struct at the end of the common FW status.
Add a convenience "counters" struct inside the FW status.
The wl12xx family does not currently use the FW status private data.

An aligned data buffer is such where the Ethernet portion of the packet
starts on a 4-byte boundary. Some chip families support padding the Rx
data buffer to achieve such alignment, others rely on the host to perform
it.
Implement the HW op for getting alignment state in wl12xx. Add
support for HW-padded alignment in the Rx flow.

For chip-families that support aligned buffers in the Rx side. The Rx
flow changes slightly for these chips.
Currently these modifications rely on a hard-coded block-size of 256.

Rename the wl12xx driver directory to wlcore as an initial step
towards the split of the driver into wlcore and wl12xx. We just
rename the directory first to keep git blame happy.
