Since usb bus add extra delay on each request, a command
with read + write requests is too expensive. We can dramtically
reduce usb load by moving this command to firmware.
In my tests, this patch will reduce channel scan time
for about 5-10 seconds.

Seems H/W report correctly firmware Autorun value only at initialization
stage. When we close interface and open it again, Autorun value is 0 and
we try to load firmware what kills the device. To fix clear
REQUIRE_FIRMWARE firmware flag, to do not load firmware again, once we
discover Autorun mode.

With patch '960d6d08e39 "mwifiex: delay skb allocation for RX
until cmd53 over"' we no more pass skb parameter to MP aggregation setup
helper function. We instead pass length to be aggregated.
This patch fixes an issue where we were passing length parameter of NULL
skb to aggregation routine resulting into crash. We should instead pass
rx_len received from mp_regs.

Recently support was added for the BCM4345 SDIO chipset by
commit 9c51026509d7 ("brcmfmac: Add support for BCM4345 SDIO chipset")
however this was verified using a BCM43455 device, which is
a more recent revision of the chip. This patch assure that
older revisions are not probed as they would fail.

SDIO uses a thread to handle all communication with the device,
for this data is exchanged between threads. This data needs proper
memory barriers to make sure that data "exchange" is going correct.

Several host controllers supporting runtime-pm are causing issues
with our sdio wireless cards because they disable the sdio interrupt
upon going into runtime suspend. This patch avoids that by doing
a pm_runtime_forbid() call during the probe. Tested with Sony Vaio
Duo 13 which uses sdhci-acpi host controller.

Multicast is not yet properly supported for all connection types;
actually, only non-secure AP is supported. For all other cases,
fall back to old "pseudo-DMS" approach. Namely, for:
- PBSS
- secure connection
When re-routing MCAST Rx->Tx on the AP, do not Tx back to the origin

For the networking code and for hardware network accelerators,
it is better to have IP header 4*n aligned. On the other side,
DMA on Rx path require buffer to be aligned on 4*n as well.
Having 14 bytes of Ethernet header, these 2 alignment
requests are in contradiction.
To solve this, order hardware offload block to not remove
SNAP header. This adds extra 6 bytes between addresses and
ethertype, making it 20 bytes total. This way, both buffer and
IP header are 4*n aligned. Remaining is only to remove SNAP
by shifting addresses 6 bytes. This involves data copying, so
this feature should be disabled unless required by the platform.
Module parameter "rx_align_2" (bool, default - false)
introduced to control this feature. Feature is completely disabled
when parameter is false.

I've been getting this error when building mainline kernels using

^
cc1: some warnings being treated as errors
scripts/Makefile.build:258: recipe for target 'drivers/net/wireless/rtlwifi/rtl8188ee/hw.o' failed
I'm not sure if this is the correct fix, but it does seem to allow the
build to complete. I suspect that this was broken by commit 34ed780a6afc
(rtlwifi: Fix problems with building an allyesconfig). Most of the files
that removed the include of pwrseqcmd.h, added one for ../pwrseqcmd.h.
The rtl8188ee driver had it removed it but didn't add the include of the
file in the parent directory.

This patch brings in support for SDIO single port rx aggregation
to mwifiex.
Maximum read size support by SDIO cmd53 is 64K.
Based on multi port aggregation which is already part of mwifiex, idea here
is multiple packets received in FW can be aggregated into single buffer.
A separate upload type is defined for such packet aggregated to single port.
Packets from this single buffer are later deaggregated into individual packets.
This way, driver can receive more packets each time through single SDIO cmd53;
thereby reducing no of times MMC bus is accessed.
SDIO SP aggregation support is advertised by FW during load time and driver
would get FW block size in command response of HostCmd_CMD_SDIO_SP_RX_AGGR_CFG.

In struct wl18xx_acx_rx_rate_stat, rx_frames_per_rates field is an
array, not a number. This means WL18XX_DEBUGFS_FWSTATS_FILE can't be
used to display this field in debugfs (it would display a pointer, not
the actual data). Use WL18XX_DEBUGFS_FWSTATS_FILE_ARRAY instead.
This bug has been found by adding a __printf attribute to
