mac80211: export IE splitting function
Export ieee80211_ie_split function, so it can be reused by drivers which need to insert additional elements. Signed-off-by: Andrei Otcheretianski <andrei.otcheretianski@intel.com> Signed-off-by: Emmanuel Grumbach <emmanuel.grumbach@intel.com> Signed-off-by: Johannes Berg <johannes.berg@intel.com>

-/**
- * ieee80211_ie_split - split an IE buffer according to ordering
- *
- * @ies: the IE buffer
- * @ielen: the length of the IE buffer
- * @ids: an array with element IDs that are allowed before
- * the split
- * @n_ids: the size of the element ID array
- * @offset: offset where to start splitting in the buffer
- *
- * This function splits an IE buffer by updating the @offset
- * 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 @ielen if the entire (remainder)
- * of the buffer should be used.
