Function Documentation

void process_packet ( struct jbuf *  jb,
flow_entry_t flow,
uint16_t  ssid 
)

Process an IP packet that is UDP, and the UDP header must be available in the bytes following the IP address.

Parameters:
[in] jb The received jbuf for this packet
[in] flow The flow state
[in] ssid The service set id

status_t pullup_bytes ( struct jbuf **  pkt_buf,
uint16_t  num_bytes 
)

Ensure or pullup enough data into the first jbuf of the chain in order to analyze it better where the bytes are contiguous

Parameters:
[in] pkt_buf The packet in jbuf format (chain of jbufs)
[in] num_bytes The number of contiguous bytes of data required in the first jbuf
Returns:
Returns the result of the jbuf_pullup on the pkt_buf upon SUCCESS; otherwise pkt_buf remains unchanged and EFAIL is returned
