New IOAM6 encap type for routes
This patch provides a new encap type for routes to insert an IOAM pre-allocated
trace:
$ ip -6 ro ad fc00::1/128 encap ioam6 trace prealloc type 0x800000 ns 1 size 12 dev eth0
where:
- "trace" and "prealloc" may appear as useless but just anticipate for future
implementations of other ioam option types.
- "type" is a bitfield (=u32) defining the IOAM pre-allocated trace type (see
the corresponding uapi).
- "ns" is an IOAM namespace ID attached to the pre-allocated trace.
- "size" is the trace pre-allocated size in bytes; must be a 4-octet multiple;
limited size (see IOAM6_TRACE_DATA_SIZE_MAX).
