Detailed Description

cofpacket

• contains a packet from OpenFlow protocol
• provides container for validating an OpenFlow packet
• stores during validation actions, matches, instructions, buckets, ofports in appropriate containers
• stores pointer to cofbase entity the packet was received from (either cfwdelem or cofrpc)
