Hello,
This patch corrects the behavior when an OFPAT_PACKET_OUT is received
and the in_port is in the output action list. In these cases packets
should not be sent to the corresponding output if it matches the
in_port (i.e just like in the case with action=OFPP_FLOOD, the packet
is not also sent to in_port).
Example:
OFPT_PACKET_OUT (xid=0x0): in_port=LOCAL actions_len=16
actions=output:1,LOCAL data_len=60
This packet is output to ports 1 and LOCAL,but should just output to port 1.
Thanks,
Aaron
