Expose this in nl80211 through the new attributes NL80211_ATTR_WIPHY_FREQ_OFFSET, NL80211_FREQUENCY_ATTR_OFFSET, NL80211_ATTR_CENTER_FREQ1_OFFSET, and NL80211_BSS_FREQUENCY_OFFSET. These add support to send and receive a KHz offset component with the following NL80211 commands: - NL80211_CMD_FRAME - NL80211_CMD_GET_SCAN - NL80211_CMD_AUTHENTICATE - NL80211_CMD_ASSOCIATE - NL80211_CMD_CONNECT Along with any other command which takes a chandef, ie: - NL80211_CMD_SET_CHANNEL - NL80211_CMD_SET_WIPHY - NL80211_CMD_START_AP - NL80211_CMD_RADAR_DETECT - NL80211_CMD_NOTIFY_RADAR - NL80211_CMD_CHANNEL_SWITCH - NL80211_JOIN_IBSS - NL80211_CMD_REMAIN_ON_CHANNEL - NL80211_CMD_JOIN_OCB - NL80211_CMD_JOIN_MESH - NL80211_CMD_TDLS_CHANNEL_SWITCH If the driver advertises a band containing channels with frequency offset, it must also verify support for frequency offset channels in its cfg80211 ops, or return an error.
