I think is not a MTU problem, the MTU is same for all kernel I use

kernel 4.10.17 or previous
    ping (ICMP): work
    host (UDP) : work
    ssh (TCP)  : work
    ftp (TCP)  : work
    smb (TCP)  : work

kernel 4.11.3-200 and  4.11.3-201    
    ping (ICMP): work
    host (UDP) : work
    ssh (TCP)  : NOT work
    ftp (TCP)  : NOT work
    smb (TCP)  : NOT work

I have fill a bugzilla:
https://bugzilla.redhat.com/show_bug.cgi?id=1458222#c2

Thanks
