This adjusts the output of bgpctl show fib. It removes the F_DOWN check
since kroutes no longer track this. And it changes the flag printing code
to reserve the space needed so that adjusting the flags does not break the
output. Last but not least increase the size of destination and gateway to
32bytes so that more IPv6 addrs fit.
Before:
> bgpctl show fib con
flags: * = valid, B = BGP, C = Connected, S = Static
N = BGP Nexthop reachable via this route
r = reject route, b = blackhole route
flags prio destination gateway
*CN 4 10.83.0.0/24 link#1
*C 1 10.83.66.5/32link#4
After:
> bgpctl show fib con
flags: B = BGP, C = Connected, S = Static
N = BGP Nexthop reachable via this route
r = reject route, b = blackhole route
flags prio destination gateway
CN 4 10.83.0.0/24 link#1
C1 10.83.66.5/32link#4
