Subject: Fixes another bug in packet retransmissions.
X-Git-Tag: v1.2.0~141
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=a9dc5e1ef2fd08c53bceb54690f6dac83ddf0c81;p=thirdparty%2Fbird.git

Fixes another bug in packet retransmissions.

When slave was in full state, it didn't retransmit
lost packets. That leads to OSPF connection locked
in states loading-full.
