As Ken mentioned, the first packet sent by the client in any call will
(in practice) have sequence number 1, and have the CLIENT_INITIATED
flag set (and of course it has to be a data packet).  If the argument
list is long, it could spill over to the next packet, and if the call
is a streaming one, the same packet could also include the variable
length payload.
