Data Fields
union NetAddr	src_ip
union NetAddr	dst_ip
uint16_t	src_port
uint16_t	dst_port
uint32_t	padding

Detailed Description

Packet flow information.

All fields are in network byte order, that is, port numbers must be swapped to check against values. For example, test if port is 1234 as follows:

struct Flow flow;
packet_flow(ctx, &flow);
if (flow.dst_port == bswap16(1234)) { ... }
