pimd: Add ability to set DR Priority for an interface From RFC 4601, Section 4.3.1: The DR_Priority Option allows a network administrator to give preference to a particular router in the DR election process by giving it a numerically larger DR Priority. The DR_Priority Option SHOULD be included in every Hello message, even if no DR Priority is explicitly configured on that interface. This is necessary because priority-based DR election is only enabled when all neighbors on an interface advertise that they are capable of using the DR_Priority Option. The default priority is 1. This modification allows the setting of the DR Priority on a per interface basis. Signed-off-by: Donald Sharp <sharpd@cumulusnetworks.com>
