Ubuntu kernel building with Atheros hambands 2.3Ghz patch

Ubuntu 16.04 LTS  kernel building with Atheros hambands 2.3Ghz patch and wireless-regdb update

This solution allows to limit interference with the 2.4GHz TARANIS radio  when Wifibroadcast for video is activated.

  • You must add these three patches available into archive file atheros_hambands.tgz over Linux kernel source (manually) before to start compilation  (the fourth patch is for hostapd : not used here) :
  1. htc_drv_init.c.patch
  2. regd.c.patch
  3. util.c.patch
