2.2.15-pre2 has
o Network fix kit (Dave Miller and co)
        | Nagle improvements, TCP_CORK/FIN fix
        | /proc/net/tcp reports type 4 for timer
        | Fix TIME_WAIT logic
        | Clean up timer performance
        | Handle shutdown() in CLOSE_WAIT right
        | Report state change on tcp_fin after setting
        | new state
        | Shutdown on close in write_err case (Paul Russell)

So yes there are some. If 2.2.15pre2 fixes your case do let me know
