+Subject: [PATCH 49/50] iw: fix cmd_size determination with LTO
+
+Use a separate section to determine the cmd_size as in LTO
+the entries in __cmd get freely rearranged, leading to a
+(usually) very large cmd_size, and thus to the whole thing
+not working.

+%description
+iw is a new nl80211 based CLI configuration utility for wireless devices.
+It supports all new drivers that have been added to the kernel recently.
+The old tool iwconfig, which uses Wireless Extensions interface,
+is deprecated and it's strongly recommended to switch to iw and nl80211.
