[PATCH] fix src address for rip with IPv4

[Roman Hoog Antink]

This patch fixes RIP under Linux with IPv4 (IPv6 not tested).

RIP could not send packets under Linux/IPv4 because the source address
was set to the multicast destination address or the broadcast address
respectively.
This resulted in the following error when sending out the first packet:
  Unexpected error at rip transmit: Invalid argument
Eventually no RIP packet could leave the host.
