From 5e6e43eb20639aa8003794c076677c188ac01b3a Mon Sep 17 00:00:00 2001 From: Amitkumar Karwar Date: Fri, 7 Mar 2014 19:41:30 -0800 Subject: [PATCH] mwifiex: create separate function mwifiex_11n_dispatch_pkt() Existing mwifiex_11n_dispatch_pkt() function is renamed as mwifiex_11n_dispatch_pkt_until_start_win() and a new function mwifiex_11n_dispatch_pkt() is created for a common code which dispatches single packet based on interface type.
