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.
