Test with dig

[yifan513]

Can the xdp be tested with dig? Such as dig @127.0.0.1 foo.bar after ip link ... and xdns add ...
Currently I got timeout as below.

.../xpress-dns/src# ip link show dev eth0
2: eth0: <BROADCAST,MULTICAST,UP,LOWER_UP> mtu 1500 xdp qdisc fq_codel state UP mode DEFAULT group default qlen 1000
link/ether 00:16:3e:82:b5:d2 brd ff:ff:ff:ff:ff:ff
prog/xdp id 125 name xdp_dns tag 060f1fbb51fad662 jited

.../xpress-dns/src# ./xdns list
A foo.bar 127.0.0.1 120

.../xpress-dns/src# dig @127.0.0.1 foo.bar

; <<>> DiG 9.16.1-Ubuntu <<>> @127.0.0.1 foo.bar
; (1 server found)
;; global options: +cmd
;; connection timed out; no servers could be reached

Any suggestion?
