Subject: client: ALlow keepalive only mode
X-Git-Tag: 0.1.0~45
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=79a2c4d724346d89e71eeab82df83b36214a59b1;p=fireperf.git

client: ALlow keepalive only mode

In this mode, the client won't send any data and only hold the
connections open.
