Subject: mac802154: remove mac_params in sdata
X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=5fb3f026ae15827fe32e34adafce0d0f63ad0366;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

mac802154: remove mac_params in sdata

This patch removes the mac_params from subif data struct. Instead we
manipulate the wpan attributes directly.
