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

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

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

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 34ed780a
(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
