net: sched: allow flower to match erspan options
This patch is to allow matching options in erspan.
The options can be described in the form:
VER:INDEX:DIR:HWID/VER:INDEX_MASK:DIR_MASK:HWID_MASK.
When ver is set to 1, index will be applied while dir
and hwid will be ignored, and when ver is set to 2,
dir and hwid will be used while index will be ignored.
Different from geneve, only one option can be set. And
also, geneve options, vxlan options or erspan options
can't be set at the same time.
