> This patch adds support for IGMPMSG_WRVIFWHOLE which is used to pass > full packet and real vif id when the incoming interface is wrong. > While the RP and FHR are setting up state we need to be sending the > registers encapsulated with all the data inside otherwise we lose it. > The RP then decapsulates it and forwards it to the interested parties. > Currently with WRONGVIF we can only be sending empty register packets > and will lose that data. > This behaviour can be enabled by using MRT_PIM with > val == IGMPMSG_WRVIFWHOLE. This doesn't prevent IGMPMSG_WRONGVIF from > happening, it happens in addition to it, also it is controlled by the same > throttling parameters as WRONGVIF (i.e. 1 packet per 3 seconds currently). > Both messages are generated to keep backwards compatibily and avoid > breaking someone who was enabling MRT_PIM with val == 4, since any > positive val is accepted and treated the same. > > Signed-off-by: Nikolay Aleksandrov <niko...@cumulusnetworks.com> Applied.
