The number of packets received from the client on this connection with a
positive data length (e.g., pure control packets do not count). This
may include spurious retransmissions.

Unlike `client.socket.tcpi_segs_in`, `client.socket.tcpi_data_segs_in` excludes segments carrying no data (e.g., pure ACK).
