ieee80211_ie_split - split an IE buffer according to ordering

: the IE buffer : the length of the IE buffer : an array with element IDs that are allowed before the split : the size of the element ID array : offset where to start splitting in the buffer

This function splits an IE buffer by updating the variable to point to the location where the buffer should be split.

It assumes that the given IE buffer is well-formed, this has to be guaranteed by the caller!

It also assumes that the IEs in the buffer are ordered correctly, if not the result of using this function will not be ordered correctly either, i.e. it does no reordering.

The function returns the offset where the next part of the buffer starts, which may be if the entire (remainder) of the buffer should be used.

void ieee80211_resume_disconnect ( struct ieee80211_vif * vif )

ieee80211_resume_disconnect - disconnect from AP after resume

: &struct ieee80211_vif pointer from the add_interface callback.

Instructs mac80211 to disconnect from the AP after resume. Drivers can use this after WoWLAN if they know that the connection cannot be kept up, for example because keys were used while the device was asleep but the replay counters or similar cannot be retrieved from the device during resume.

Note that due to implementation issues, if the driver uses the reconfiguration functionality during resume the interface will still be added as associated first during resume and then disconnect normally later.

This function can only be called from the resume callback and the driver must not be holding any of its own locks while it calls this function, or at least not any locks it needs in the key configuration paths (if it supports HW crypto).

struct ieee80211_hw* wiphy_to_ieee80211_hw ( struct wiphy * wiphy )

read

wiphy_to_ieee80211_hw - return a mac80211 driver hw struct from a wiphy

: the &struct wiphy which we want to query

mac80211 drivers can use this to get to their respective &struct ieee80211_hw. Drivers wishing to get to their own private structure can then access it via hw->priv. Note that mac802111 drivers should not use wiphy_priv() to try to get their private driver structure as this is already used internally by mac80211.
