002-openwrt4716-TARGET_brcm4716-deps.patch
fix bcm4716 package dependencies:
* broadcom-diag
~ let it get built for bcm4716 target.
* broadcom-wl
~ let it get built for bcm4716 target, make it working with bcm4716 attached w11 core.
* kernel
~ don't let select ssb to be built as module for bcm4716 target.
~ add gmac driver for bcm4716 target.
* mac80211
~ don't let it be selected with bcm4716 target - you will fail to build it, and even if
you succeede with b43 still it don't support bcm4716' w11 N-Phy core yet.
* nvram
~ let it get built for bcm4716 target.
* switch
~ let it get built for bcm4716 target.
