This patch provides support for adding, listing and removing IOAM namespaces
and schemas with iproute2. When adding an IOAM namespace, both "data" (=u32)
and "wide" (=u64) are optional. Therefore, you can either have none, one of
them, or both at the same time. When adding an IOAM schema, there is no
restriction on "DATA" except its size (see IOAM6_MAX_SCHEMA_DATA_LEN). By
default, an IOAM namespace has no active IOAM schema (meaning an IOAM namespace
is not linked to an IOAM schema), and an IOAM schema is not considered
as "active" (meaning an IOAM schema is not linked to an IOAM namespace). It is
possible to link an IOAM namespace with an IOAM schema, thanks to the last
command below (meaning the IOAM schema will be considered as "active" for the
specific IOAM namespace).

$ 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 }
