linux-cp: Fix add vs update on routes
Linux uses NLM_F_REPLACE in the netlink message to signal a FIB update
The code invariably does a FIB update for IPv4 and a addition for IPv6.
Without this fix, the following:
ip route add 2001:db8::/48 via 2001:db8::1
ip route replace 2001:db8::/48 via 2001:db8::2
ends up as two separate FIB entries in VPP. With the fix, there will be one FIB entry (the second one with nexthop ::2).
Type: fix
