Resolved the iwlwifi conflict with mainline using 3-way diff posted
by John Linville and Stephen Rothwell.  In 'net' we added a bug
fix to make iwlwifi report a more accurate skb->truesize but this
conflicted with RX path changes that happened meanwhile in net-next.

In e1000e a conflict arose in the validation code for settings of
adapter->itr.  'net-next' had more sophisticated logic so that
logic was used.

6bac40a63a wlcore/wl12xx: adapt FW status for multiple families
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.

5453dc105a wlcore/wl12xx: use a single memory config and reset if using wl127x
Instead of having two memory configuration sets, one for wl127x and
one for wl128x, we can use only one which should be correctly set by

f83985bb5f wlcore/wl12xx: turn no-Tx-align quirk into Tx-align
Inverting the quirk flag to indicate Tx-alignment. This aligns it with
the similar Rx-side quirk.

The call to wl1271_set_block_size() decides whether SDIO block size
alignment can be used or not.  In case we're using SPI, we can't use
the block size alignment, so the function returns false.  So we set
the quirk when wl1271_set_block_size() returns true and let the wl12xx
lower driver unset the bit for wl127x (since it doesn't support this
quirk).

53d67a50cd wlcore/wl12xx: split Tx completion to immediate/delayed
One chip family employs immediate Tx completion, where knowledge of
completed packets is given as part of the FW status. Another is only
notified of Tx completion via the FW status, and has to read the
completion status of the packets from a different location.

b14684a004 wlcore/wl12xx: add prepare_read hw op for Rx data
The only difference in the read_data operations is that some chips
need to prepare the data to be read before reading.  So instead of
having a mandatory read_data operation, we now have an option
prepare_data operation that only needs to be implemented for chips
that require it.

In the wl12xx lower driver, we only set the prepare_data operation for
wl127x chips.
