From 38af0423cbbc4c9acee71a197eec7089d1d1b9d3 Mon Sep 17 00:00:00 2001 From: Jouni Malinen Date: Sat, 9 Jan 2016 00:47:30 +0200 Subject: [PATCH] Drop OpenSSL 0.9.8 patches to add EAP-FAST support The OpenSSL project will not support version 0.9.8 anymore. As there won't be even security fixes for this branch, it is not really safe to continue using 0.9.8 and we might as well drop the EAP-FAST patches for it.
