Return a double vlan tagged dataplane UDP packet
Supports a few parameters:
@param len Length of packet in bytes w/o CRC
@param eth_dst Destination MAC
@param eth_src Source MAC
@param dl_vlan_enable True if the packet is with vlan, False otherwise
@param c_vlan_vid CVLAN ID
@param c_vlan_pcp CVLAN priority

Generates a simple UDP packet. Users shouldn't assume anything about
