Subject: MEDIUM: h2: always subscribe to receive if allowed.
X-Git-Tag: v1.9-dev2~31
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a1411e62e4da1c4013539b58e2e46d2fcc239a9c;p=thirdparty%2Fhaproxy.git

MEDIUM: h2: always subscribe to receive if allowed.

Let the connection layer know we're always interested in getting more data,
so that we get scheduled as soon as data is available, instead of relying
on the wake() method.
