#define FLAG_SET (   vector,
)    ((vector) & (flag))


Called to processes a tcp packet from either process_ip4() or process_ip6(). The caller breaks out the ip addresses and finds the start of the tcp header.

Skips but otherwise ignores TCP options.

creates a new tcp connection if necessary, then asks the connection to either print the packet or store it.

Returns 0 if packet is processed, 1 if it is not processed, -1 if error
