From: Li Chaoming <chaoming_li@xxxxxxxxxxxxxx> Realtek driver version rtl_92ce_92se_92de_linux_mac80211_0005.1230.2011 includes a number of changes in rtl8192ce. The main differences are as follows: 1. Include code for a number of new versions. 2. Update the signal strength reporting. 3. Update to handle 802.11w encryption correctly.
