Subject: Filters: Function body comparison result now used.
X-Git-Tag: v2.0.7~19
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3f477ccb03ed99cf6754baaca179fcf791bcda55;p=thirdparty%2Fbird.git

Filters: Function body comparison result now used.

Function bodies were compared in post-parse time, yet the result was not
used and the functions were incorrectly considered the same as before.

Now the result is used to reload affected protocols.
