EtherEncap(ETHERTYPE, SRC, DST)

=s encapsulation, Ethernet

encapsulates packets in Ethernet header

=d

Encapsulates each packet in the Ethernet header specified by its arguments.
ETHERTYPE should be in host order.

=e

Encapsulate packets in an Ethernet header with type
ETHERTYPE_IP (0x0800), source address 1:1:1:1:1:1, and
destination address 2:2:2:2:2:2:

  EtherEncap(0x0800, 1:1:1:1:1:1, 2:2:2:2:2:2)

=n

For IP packets you probably want to use ARPQuerier instead.

=h src read/write

Returns or sets the SRC parameter.

=h dst read/write

Returns or sets the DST parameter.

=a
