We are using mirroring on a switch that can send the mirrored packets via GRE. But this means that the complete packet including the Ethernet header will be part of the payload. It would be nice if this could be encapsulated and only keeping the payload Ethernet header.

Like:

     +----------------+
     | Ethernet head. |
     +----------------+
     |   IP header    |
     +----------------+
     |   GRE header   |
     +----------------+
     |+--------------+|                            +--------------+
     ||Ethernet head.||                            |Ethernet head.|
     |+--------------+|                            +--------------+
     ||  IP header   ||  +-------ipdecap-------->  |  IP header   |
     |+--------------+|                            +--------------+
     ||   Payload    ||                            |   Payload    |
     |+--------------+|                            +--------------+
