X-Git-Url: https://git.stricted.de/?a=commitdiff_plain;h=0eabccd940f0f25da0ae29e555fddb8fb84d8e27;p=GitHub%2FLineageOS%2FG12%2Fandroid_kernel_amlogic_linux-4.9.git

When AP interface is stopped ssid_len in the BSS configuration
isn't cleared which can confuse drivers when switching modes.
Set the length to zero when stopping the AP interface.
