pimd: MLAG flag defintions in the PIM upstream entries
Two flags have been introduced per-upstream entry -
1. XXX_MLAG_VXLAN - This indicates that MLAG DF (designated-forwarded)
election is needed on the entry. In the case of pim-evpn this flag is set
for termination (*, G) entries and will be inherited by the (S, G) entries
that are created as a result of SPT switchover on the G.
2. XXX_MLAG_NON_DF - This is set on entries that have lost the
DF election. Such entries are primarily used for blackholing traffic on
one of the MLAG switches. On a hardware accelerated switch this blackholing
happens in the ASIC preventing (non-needed) traffic hitting the CPU.
