Hey list,
when OVS sends frames to the controller using PACKET_IN PDUs, it looks
like [1].
The OF1.3 spec says, that the switch must support context fields like
OFB_IN_PORT - others are optional.
Do you plan to support some or all of the fields like ETH_SRC and
ETH_DST and ETHER_TYPE as a courtesy to the controller, so no additional
packet parsing is needed?
OT and wrong list, but I would also like to see the parsed context
fields being configured by the controller, as it would make no sense to
parse a whole PDU down to port numbers, when I just consume ethernet
fields. What do you think?
