Subject: openssl: add option to disable compression support
X-Git-Url: http://git.lede-project.org./?a=commitdiff_plain;h=eb4fc91a81f01a0ea3dd7f3bd0230f1c5eca67c6;p=openwrt%2Fstaging%2Flynxis.git

openssl: add option to disable compression support

By default it's disabled. After the CRIME attack it seems the use of
compression is discouraged.
