This patch fixes multiple issues with the current RTT

* The data that is obtained from the RTT interface registers
are stored in 31:5 - mask out the extra bits when reading them.
* A history buffer is maintained which is not needed at all.
Remove this array and just store the baseband data for each
chain (or bank).
* A 'num_readings' variable was being used to handle the
last entry. But it was being used in an improper manner, with
the result that the RTT values were never being written
to the RTT Interface registers. Fix this by using a simple
flag.

mac80211_hwsim: Fix rate control by correctly reporting transmission counts
Drivers need to report the number of transmission attempts for each rate
as well as to terminate the rate array with -1. The in-kernel datapath
of hwsim simulates a perfect medium, therefore the driver only needs to
report that the first transmission attempt was sucessfully completed at
the most favorable rate.
Rate control is working again for this driver. Tested mesh mode with
minstrel.

{nl,cfg,mac}80211: Allow user to see/configure HT protection mode
This patch introduces a new mesh configuration parameter "ht_opmode" and will
allow user to check the current HT protection mode selected. Users could
configure the protection mode by the command "iw mesh_iface set mesh_param
mesh_ht_protection_mode=2". The default protection mode of mesh is set to
non-HT mixed mode.

mac80211: Implement HT mixed protection mode
Section 9.23.3.5 of IEEE 80211s standard describes the protection rules for
HT mesh STA in a MBSS. Three HT protection modes are supported for now:
non-HT mixed mode - is selected if any non-HT peers are present in our MBSS.
20MHz-protection mode - is selected if all peers in our 20/40MHz MBSS support
HT and atleast one HT20 peer is present.
no-protection mode - is selected otherwise.
This is a limited implementation of 9.23.3.5, which only considers mesh peers
when determining the HT protection mode. Station's channel_type needs to be
maintained.

cfg80211: fix BSS comparison
Since the BSS table is organized in a RB tree, the BSSs need to be
comparable. This means that we must define a < and > operator to
the BSS object.
compare_ethr_addr isn't enough since it returns only a binary value.

Because of the constant size and guaranteed 16 bit alignment, the inline

The BSS table is corrupted: rb_find_bss can't find the bss.
As a result BSSes are duplicated in the BSS table, and we get stuck
while probing an AP before associating (in STA mode).

brcmfmac: add out of band interrupt support
Some sdio host controllers do not support real in band interrupt.
Software polling mode as a replacement is not fast enough for
high throughput and new features. Also some in band interrupts
do not support host wake up on embedded platform even when they
are real physical interrupts. Therefore out of band (oob)
interrupt mechanism is implemented for these scenarios.
To provide oob irq number and flags used for irq registration in
brcmfmac, a platform device contains irq resource must be
registered in board specific code.
Here is an example of platform device structure:
struct resource brcmf_sdio_res[] = {
{
.start = GPIO_BRCMF_SDIO_OOB_NUM,
.end = GPIO_BRCMF_SDIO_OOB_NUM,
.flags = IORESOURCE_IRQ | IORESOURCE_IRQ_HIGHLEVEL,
}
};
struct platform_device brcmf_sdio_device = {
.name = "brcmf_sdio_pd",
.id = -1,
.num_resources = ARRAY_SIZE(brcmf_sdio_res),
.resource = brcmf_sdio_res,
};
