Hi Dan,

Patch looks good, although it does not apply to current libertas-2.6
tree.

Also, where is DEFAULT_MAX_SCAN_AGE defined? Can't find it in the patch.

+       /* Prune old entries from scan table */
+       list_for_each_entry_safe (iter_bss, safe, &adapter->network_list, list) {
+               unsigned long stale_time = iter_bss->last_scanned + DEFAULT_MAX_SCAN_AGE;
+               if (time_before(jiffies, stale_time))
+                       continue;
+               list_move_tail (&iter_bss->list, &adapter->network_free_list);
+               clear_bss_descriptor(iter_bss);
+       }
