Subject: lacp: Remove heartbeat mode.
X-Git-Url: https://pintos-os.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=b20a8f7c11fbff647cc65cc3db22a22e5d5cad0b;p=openvswitch

lacp: Remove heartbeat mode.

The LACP heartbeat mode was used to monitor interfaces for
connectivity.  It turns out that LACP is inferior to CFM for this
purpose.  For the sake of simplicity this patch removes the
feature.
