    A few more data points: dd from a local zvol to a local zvol on either
    machine works fine.

    Using nc instead of ssh, this time it's the sender nc dying:

    ktrace on the sender:

    47704 nc       CALL  write(0x3,0x7fffffff5450,0x800)
    47704 nc       RET   write -1 errno 32 Broken pipe
    47704 nc       PSIG  SIGPIPE SIG_DFL code=0x10006

    truss on the sender:

    poll({3/POLLIN 0/POLLIN},2,-1)                   = 2 (0x2)
    read(3,0x7fffffff5450,2048)                      ERR#54 'Connection reset by peer'
    close(3)                                         = 0 (0x0)


    On tcpdump, I do see the receiver send a FIN when using nc.
    When using ssh, the sender is sending the FIN.

    Anything else I can look for ?
