Subject: MINOR: proxy: make pr_mode enum bitfield compatible
X-Git-Tag: v3.2-dev7~30
X-Git-Url: http://git.ipfire.org/?a=commitdiff_plain;h=d9aa1991006a6d7348e24af0ea781337d5b1c722;p=thirdparty%2Fhaproxy.git

MINOR: proxy: make pr_mode enum bitfield compatible

Current pr_mode enum is a regular enum because a proxy only supports one
mode at a time. However it can be handy for a function to be given a
list of compatible modes for a proxy, and we can't do that using a
bitfield because pr_mode is not bitfield compatible (values share
the same bits).

In this patch we manually define pr_mode values so that they are all
using separate bits and allows a function to take a bitfield of
compatible modes as parameter.
