[Q] Custom CyanogenMod Kernel (Samsung S3 i9300) - mac80211 Drivers - Galaxy S III Q&A, Help & Troubleshooting

Hi Everyone
I am fairly new to android customisation, rooting, etc. and have been playing around with creating a custom CyanogenMod kernel to support a TP-Link USB wifi dongle.
The primary reference article for this can be found here - http://forum.xda-developers.com/showthread.php?t=2338179. However I have made some changes as listed below.
Keen to hack this further and any advice or guidance will be greatly appreciated.
Technical Spec:
Ubuntu 12.04 (32 Bit)
Samsung S3 (Cyanogenmod ROM)
Kernel = https://github.com/CyanogenMod/android_kernel_samsung_smdk4412
.config = https://github.com/CyanogenMod/andr.../arch/arm/configs/cyanogenmod_i9300_defconfig
Note - There is no /proc/config.gz on my device, hence the above use of the config.
gcc-arm-linux-gnueabi libstdc++6 libncurses5 libncurses5-dev - exports correctly setup.
Objective
Getting an TP-Link TL-WN821N USB Wifi Dongle to work.
The relevant drivers are already available in mac80211 - http://www.aircrack-ng.org/doku.php?id=mac80211

Exactly the same issue here, bump :/

When I had to build a mac80211 driver (rt2800usb), I had to apply the following changes on top of cm-10.2.0 (d6f2f4ae4e593067dc59e2ac63f022434199f673):
Code:
# Depends on 3.4 backport that breaks mac80211.
git revert d6f2f4ae4e593067dc59e2ac63f022434199f673 # "Add support for Note 8 (N5100 and N5110)"
git revert c421809918b7106b40a81134f9fb5103146fc715 # "update bcmdhd driver from GT-9505 Source"
git revert 44655588a0b361afa15761b5c58f5a558c1c181c # "WIFI: Use kernel version 3.4 ifdef's."
git revert 3cedbff33e9884fdf3f7aaaa83ab9774d8145d1f # "wireless backport from 3.4"
# Another build fix:
Date: Sun Nov 24 12:04:33 2013 +0100
lib: fix compile of lib/genalloc.c
Taken from commit 3cedbff ("wireless backport from 3.4").
lib/genalloc.c | 54 ++++++++++++++++++++++++++++++++----------------------
1 file changed, 32 insertions(+), 22 deletions(-)
After that I was able to build rt2x00 from 3.4.70 (after enabling MAC80211 in config).. Note: these patches do not seem to revert cleanly on cm-11.0
For cm-11.0 (HEAD was 22cbf2cfb211cef2e493c5984d237d0509bf98ce, "otg: when removing ED from readyQ also set flag"), I now do:
Code:
# v--- 2014-11-06 (CM 11.0)
- revert c421809 # update bcmdhd driver from GT-9505 Source
Conflict in drivers/net/wireless/bcmdhd/Makefile, remove -DPASS_IPV4_SUSPEND
and DEBUGFS_CFG80211 (unused), all that remains is:
DHDCFLAGS += -DBLOCK_IPV6_PACKET
Conflict in drivers/net/wireless/bcmdhd/dhd_sec_feature.h, remove:
CONFIG_MACH_KONA
.config:
BCMDHD=M (was =Y, but this allows debugging)
DHD_USE_STATIC_BUF=N
DHD_USE_SCHED_SCAN=N
- revert 4465558 # WIFI: Use kernel version 3.4 ifdef's.
- revert 3cedbff # wireless backport from 3.4
- git checkout 3cedbff -- include/linux/{export,module}.h lib/genalloc.c
git commit -m 'Build fixes from 3cedbff'
Compile fixes, also used by d90b43b "mali: add r3p1 for devices that need it"
This compiles (with CONFIG_MAC80211=M), I have yet to try the newer rt2x00 for my purposes.
