I was going to apply this and patch 4 squashed, saying:
cfg80211: regulatory: handle 6 GHz power spectral density (PSD)
6 GHz regulatory domains introduce power spectral density (PSD).
Allow wiphy-specific regulatory rules to specify these values.
but ...

This is obviously wrong?

Yes it should change like this: if ((rrule1->flags & NL80211_RRF_PSD) && (rrule1->flags & NL80211_RRF_PSD)) chan->psd = min_t(s8, rrule1->psd, rrule1->psd); else chan->flags &= ~NL80211_RRF_PSD; > > johannes

The power spectral density(psd) of regulatory rule should be take effect to the channels. This patch is to save the values to the channel which has psd value. Signed-off-by: Wen Gong <wgong@codeaurora.org> --- net/wireless/reg.c | 14 ++++++++++++++ 1 file changed, 14 insertions(+)
