It doesn't tell you that on 2.2. It tells you there how many bytes are still
free in the send queue (send buffer size - allocated bytes including metadata),
which was clearly a bug. 2.4 instead tells you how many bytes are unacked
which makes a lot more sense. If the connection is not established that
number is zero.
