MarkMACHeader

sets MAC header annotation

SYNOPSIS§

MarkMACHeader([OFFSET, LENGTH])

Batching: Batching natively supported
Ports: 1 input, 1 output
Processing: agnostic

DESCRIPTION§

Sets the MAC header annotation to start OFFSET bytes into the packet. OFFSET defaults to 0. If LENGTH is provided and non-zero, the MAC header is LENGTH bytes long, so the network header annotation is set to OFFSET+LENGTH bytes into the packet. The packet must be long enough to support the provided OFFSET.
