Also make it more like mac80211 when printing netdevs/wiphys to make reading a combined log easier. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

This will allow extending mac80211 for VHT, which is currently restricted to channel contexts since there are no drivers using that which makes it easier. As I also don't care about VHT for drivers not using the channel context API, I won't convert the previous API to VHT support. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

The old channel type is of course still supported for HT. Also change the cfg80211 channel definition struct to support these by adding the relevant fields to it (and removing the _type field.) This also adds new helper functions: - cfg80211_chandef_create to create a channel def struct given the control channel and channel type, - cfg80211_chandef_identical to check if two channel definitions are identical - cfg80211_chandef_compatible to check if the given channel definitions are compatible, and return the wider of the two This isn't entirely complete, but that doesn't matter until we have a driver using it. In particular, it's missing - regulatory checks on the usable bandwidth (if that even makes sense) - regulatory TX power (database can't deal with it) - a proper channel compatibility calculation for the new channel types Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Right now, this struct contains just the control channel and channel type, but for VHT this will change. Also, add a small inline cfg80211_get_chandef_type() so that drivers don't need to use the _type field of the new structure all the time, which will change.

This is the case, as it's used only for P2P operations right now. Rather than adding a flag to tell userspace whether or not it can actually rely on it, simplify all the code by removing the ability to use different channel types. Leave only the validation of the attribute, so that if we extend it again later (with the needed capability flag), it can't break userspace sending invalid data.

If this happens during authentication, the flag will be lost and we send HT frames, even if the channel config was set up for non-HT. This can lead to issues. Fix this by always resetting the ifmgd flags to zero when the channel context is released so that the flag resetting in ieee80211_mgd_assoc() isn't necessary. To make the code a bit easier move the call to release the channel in ieee80211_set_disassoc() to the end of the function together with the flag resetting (which needs to be at the end to avoid timers setting flags.)

This is particularly useful in the 2.4 GHz band since a frame is often received on one of the adjacent channels due to overlap. Move this code to cfg80211 so other drivers also do this. Additionally, on 5 GHz, in particular with some (possibly) upcoming changes in 802.11ai and duplicate transmissions when wider channels are used, something similar happens. So if present, also use the (primary) channel information contained in the HT operation IE. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

Fix this by checking the 40 MHz support only for the code that sets the 40 MHz channel not the complete HT code block. This also means the HT20 channel type will always be set in the changed code block so there's no need to set it in case we override the AP due to invalid IEs in the probe response/beacon. The indentation is a bit quirky, but I'm rewriting this code for VHT support so this will change again very soon. Signed-off-by: Johannes Berg <johannes.berg@intel.com>

When I looked into it, I realised that the code was completely broken as it unassigned the channel contexts when suspending, which actually means they are destroyed. Eliad Peller then pointed out that we also need to remove the channel contexts from the driver. When I looked into this, I also noticed that the code isn't handling the virtual monitor interface correctly (if it exists.) Fix this by calling just the driver methods (if they are implemented) instead of using the channel context management code. Also add reconfiguration for the virtual monitor interface.

However, there are also cases where the driver may need to request operations from userspace, e.g., when using security on the AP path. Add a new cfg80211 function for generating a TDLS operation event for drivers to request a new link to be set up (NL80211_TDLS_SETUP) or an existing link to be torn down (NL80211_TDLS_TEARDOWN).

Therefore, instead of testing for 0 (which is in fact a valid value) we should be using this invalid value to test if the tx_power is available.
