Set right channel frequencies in VHT160 mode according to the VHT160
interoperability workaround added as part of IEEE Std 802.11™-2016 in
"Table 9-252—VHT Operation Information subfields", band_center_freq2
corresponds to CCFS1 in Table 9-253. Previous implementation
(band_center_freq2 = 0 for VHT160) is only deprecated.
Enable VHT80+80 mode and set the proper peer RX nss value for VHT160
and
VHT80+80 mode.

Hi Kalle,
I checked the build. Build was successful with GCC version 4.8.
Will fix the error and update the patch.
Thanks,
