Fix ERSPAN encap to set EN bits in the header and add test case
For ERSPAN encap, both bits in the EN field of the header should be set to indicate any VLAN tag in the original Ethernet frame is preserved. Added SPAN L2 test case where the mirrored packet output is a GRE ERSPAN tunnel. Change-Id: Ie7a40992a9278469c24aa6fa9e122b4505797d10 Signed-off-by: John Lo <loj@cisco.com>
