Subject: HE: Send the AP's OBSS PD settings to the kernel
X-Git-Tag: hostap_2_10~2376
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=a84bf443887deee828a3b4422f63475709404d5c;p=thirdparty%2Fhostap.git

HE: Send the AP's OBSS PD settings to the kernel

This allows us to send the OBSS PD settings to the kernel, such that the
driver can propagate them to the hardware/firmware.
