cfg80211: consolidate passive-scan and no-ibss flags
These two flags are used for the same purpose, just combine them into a no-ir flag to annotate no initiating radiation is allowed. Old userspace sending either flag will have it treated as the no-ir flag. To be considerate to older userspace we also send both the no-ir flag and the old no-ibss flags. Newer userspace will have to be aware of older kernels. Update all places in the tree using these flags with the following semantic patch: @@ @@ -NL80211_RRF_PASSIVE_SCAN +NL80211_RRF_NO_IR @@ @@ -NL80211_RRF_NO_IBSS +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_PASSIVE_SCAN +IEEE80211_CHAN_NO_IR @@ @@ -IEEE80211_CHAN_NO_IBSS +IEEE80211_CHAN_NO_IR @@ @@ -NL80211_RRF_NO_IR | NL80211_RRF_NO_IR +NL80211_RRF_NO_IR @@ @@ -IEEE80211_CHAN_NO_IR | IEEE80211_CHAN_NO_IR +IEEE80211_CHAN_NO_IR @@ @@ -(NL80211_RRF_NO_IR) +NL80211_RRF_NO_IR @@ @@ -(IEEE80211_CHAN_NO_IR) +IEEE80211_CHAN_NO_IR Along with some hand-optimisations in documentation, to remove duplicates and to fix some indentation.
