Subject: [PATCH 3.5 04/78] mac80211: use sta_info_get_bss() for nl80211 tx and client probing

3.5.7.26 -stable review patch.  If anyone has any objections, please let me know.

------------------

From: Felix Fietkau <nbd@...nwrt.org>

commit 03bb7f42765ce596604f03d179f3137d7df05bba upstream.

This allows calls for clients in AP_VLANs (e.g. for 4-addr) to succeed
