(cherry picked from commit 681acdcc54)
Close cooperation with Lorenzo Bianconi resulted
in these patches which fix all remaining seen issues
when using dynack.
Fix link losses when:
- Late Ack's are not seen or not present
- switching from too low static coverage class to dynack on a live link
These are fixed by setting the Ack Timeout/Slottime to
the max possible value for the currently used channel width when
a new station has been discovered.
When traffic flows, dynack is able to adjust to optimal values
within a few packets received (typically < 1 second)
These changes have been thoroughly tested on ~60 offshore devices
all interconnected using mesh over IBSS and dynack enabled on all.
Distances between devices varied from <100m up to ~35km

This partitialy reverts commit f506de2cda.
Registering the GPIO chip without a parent device completely breaks the
ath9k GPIOs for device tree targets.
As long as boards using the devicetree don't have the gpio-controller
property set for the ath9k node, the unloading of the driver works as
expected.
Register the GPIO chip with the ath9k device as parent only for OF
targets to find a trade-off between the needs of driver developers and
the broken LEDs and buttons seen by users.

529c95cc15 ("mac80211: brcmfmac: fix use-after-free & possible NULL pointer dereference")
It's more than would be normally backported into a stable branch but it
seems required. Firmware loading cleanups are needed to allow fix memory
bugs in a reliable way. Memory fixes are really important to avoid
corrupting memory and risking a NULL pointer dereference.
Hopefully this stuff has received enough testing in the master.

This adds support for BBR (Bottleneck Bandwidth and RTT) TCP
congestion control. Applications (e.g. webservers, VPN client/server)
which initiate connections from router side can benefit from this.
This provide an easier way for users to use BBR by selecting /
installing kmod-tcp-bbr instead of altering kernel config and
compiling firmware by themselves.

Some of the modules in the crypto-misc package have alternate
implementations optimized for different x86 instruction set extensions,
but only one of these was built for this package until now: twofish-i586.ko
Tested with insmod, on both x86 and x86_64. The modules now have an
autoload, which they previous didn't, loading the dependencies in the
correct order.

Problem - rapsberry pi 3 b/b+ does not boot with bcm2710 images!
How Raspberry Pi boots Actualy?
When Raspberry is switched on GPU is activated.
1. GPU execute First stage bootloader from ROM.
First stage bootloader mount the FAT boot partition on the SD card
and execute second stage bootloader (bootcode.bin).
2. Second stage bootloader (bootcode.bin) activate SDRAM.
Load the GPU firmware (start.elf).
3. GPU firmware (start.elf)
a) display Rainbow splash.
b) read firmware configuration file config.txt and
split the RAM using fixup.dat.
c) loads a cmdline.txt
d) enables the CPU.
e) loads the kernel image configurable via config.txt
In your target/linux/brcm2708/image/config.txt
493 ## kernel (string)
494 ## Alternative name to use when loading kernel.
495 ##
496 #kernel=""
it is not configured!
But in your target/linux/brcm2708/image/Makefile
75 KERNEL_IMG := kernel8.img
76 DEVICE_TITLE := Raspberry Pi 3B/3B+
you have kernel8.img
GPU Firmware search order by default for a PI 3 is:
kernel8.img if found boot in 64 bit mode
kernel8-32.img if found boot in 32 bit mode
kernel7.img if found boot in 32 bit mode
kernel.img if found boot in 32 bit mode
But a PI 2 will start the search from kernel7.img and
a PI 1 only looks for kernel.img.
Оbviously the kernel has been found.
But something goes wrong and the device is restarted.
In your package/kernel/brcm2708-gpu-fw/Makefile
11 PKG_NAME:=brcm2708-gpu-fw
12 PKG_VERSION:=2017-08-08
13 PKG_RELEASE:=e7ba7ab135f5a68b2c00a919ea9ac8d5528a5d5b
boot loader is 10 monts old.
In conclusion, the best way to solve the problem is
to update the boot loader!
Fixup_cd.dat and start_cd.elf files are not necessary.
These are used when GPU memory is set to 16 MB, which disables
some GPU features.
I did not remove them just in case!
cheers

As of commit in kernel:
6104c37094 fbcon: Make fbcon a built-time depency for fbdev
framebuffer console is build in into framebuffer module and there's no
standalone fbcon module. Therefore drop the kmod-fbcon and enable
console in kmod-fb. The only targets which use these modules are imx6
and geode, both are on kernel 4.14 so no fallback for other kernels is
introduced.
Being at that this commit also fixes autoload of fbdev for x86.

First one is a fix for reporting channels to the user space. Important
for users as they could try setting invalid channel and fail to start an
interface.
Later is a support for newer FullMAC chipset firmwares.
