+Upcoming fw versions will have different max links support
+(according to the hw). Get ready for it by configuring
+wl->num_links per-hw, instead of using the const WL12XX_MAX_LINKS.
+
+However, continue using WLCORE_MAX_LINKS in order to simplify
+structs declarations (we use it in multiple bitmaps, and converting
+them to dynamic arrays is just cumbersome).
