Subject: [PATCH iproute2-next v2 0/3] Provide support for IOAM

v2:
 - Use print_{hex,0xhex} instead of print_string when possible (patch #1)

The IOAM patchset was merged yesterday (see net-next commits [1,2,3,4,5,6]).
Therefore, this patchset provides support for IOAM inside iproute2, as well as
manpage documentation. Here is a summary of added features inside iproute2.

(1) configure IOAM namespaces and schemas:

$ ip ioam
Usage:	ip ioam { COMMAND | help }
	ip ioam namespace show
	ip ioam namespace add ID [ data DATA32 ] [ wide DATA64 ]
	ip ioam namespace del ID
	ip ioam schema show
	ip ioam schema add ID DATA
	ip ioam schema del ID
	ip ioam namespace set ID schema { ID | none }
	
(2) provide a new encap type to insert the IOAM pre-allocated trace:

$ ip -6 ro ad fc00::1/128 encap ioam6 trace type 0x800000 ns 1 size 12 dev eth0
