Detailed Description
sip packet - raw format for outbound packets that are sent or scheduled for transmission Packets are linked in a list, whose head is in the struct sip_pvt they belong to. Each packet holds a reference to the parent struct sip_pvt. This structure is allocated in __sip_reliable_xmit() and only for packets that require retransmissions.
