3338084ab3 brcm80211: fmac: postpone dongle RF enabling.
BRCMF_C_UP is the command that asks the firmware to enable RF of
dongle. Some firmware initialization steps must be performed during
RF is down. Postpone BRCMF_C_UP firing until brcmf_netdev_open get
called to ensure firmware have enough time to finish
initialization.

8f1ab44d8d brcm80211: fmac: add frame header extension support
A header extension is introduced in the received frame to provide
extra space for dongle information. This won't affect current
supported chipset since the data_offset is 0. But it's necessary for
adding support for future chipset.

474a64c80e brcm80211: fmac: register primary net device with device mac address
The primary net device was registered with a primary mac address and
upon IFUP it was set to match the actual mac address from the device.
This patch changes that and moves the brcmf_add_if() call to the common
part of the driver.

badc4f0762 brcm80211: smac: resume transmit fifo upon receiving frames
There have been reports about not being able to use access-points
on channel 12 and 13 or having connectivity issues when these channels
were part of the selected regulatory domain. Upon switching to these
channels the brcmsmac driver suspends the transmit dma fifos. This
patch resumes them upon handing over the first received beacon to
mac80211.

This patch is to be applied to the stable tree for kernel versions
3.2 and 3.3.

"It's an issue brought about by GCC 4.7's partial-inlining, that ends up
splitting the udelay function just at the wrong spot, in such a way that
some sanity checks for constants fails, and we end up calling
bad_udelay.

This patch fixes the problem.  Feel free to push it upstream if it makes

The brcmsmac driver isn't a PCI driver any more, it's a bcma one.  The
PCI device has been resumed by the PCI driver (the generic PCI layer,
really), we should be resuming just our own driver state.

Also add pr_debug() calls to show that we now actually get the

61bd5e5683 brcmsmac: fix reading of PCI sprom contents
It appears that you can only read the sprom contents with aligned 16-bit
reads: anything else causes at least some versions of the broadcom
chipset to abort the PCI transaction, returning 0xff.

This apparently doesn't trigger very often, because most setups don't
use an external srom chip, and the OTP sprom loading doesn't have this
issue.  But at least the current 11" Macbook Air does trigger it, and
wireless communications were broken as a result.

fbf59108f9 brcm80211: fmac: register a dummy irq handler for SDIO function 2
When there is data available in dongle for driver to fetch, an
interrupt will be triggered and both SDIO function 1 and 2 will be
flagged by default in bcm4329. These two interrupt flags are
identical and only need to be handled once. Since there is no way
to turn off one flag from the dongle side, a dummy handler for
function 2 interrupt is placed.

In ai_attach(), space is allocated for an si_info struct. Immediately
after the allocation, routine ai_doattach() is called and that allocated
space is set to zero. As no other routine calls ai_doattach(), kzalloc()
can be utilized.

when it was a pci device driver, ie. bcm4313, bcm43224, and bcm43225.
This patch restricts the driver to 802.11 core revisions that are found
in these chipsets.
