Frank reported that table ids for very large numbers are not properly
detected:
$ ip li add foobar type vrf table 98765432100123456789
command succeeds and resulting table id is actually:
21: foobar: <NOARP,MASTER> mtu 65536 qdisc noop state DOWN mode DEFAULT group
default qlen 1000
link/ether da:ea:d4:77:38:2a brd ff:ff:ff:ff:ff:ff promiscuity 0
vrf table 4294967295 addrgenmode eui64 numtxqueues 1 numrxqueues 1
gso_max_size 65536 gso_max_segs 65535
Make the temp variable 'i' unsigned long and let the typecast to u32
happen on assignment to id.
