From da08fdfaf09f161c923c9d2b7db2fba8cc9c457c Mon Sep 17 00:00:00 2001 From: Eliad Peller Date: Mon, 10 Feb 2014 13:47:22 +0200 Subject: [PATCH] wlcore/wl12xx/wl18xx: configure num_links per-hw 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).
