Yes indeed, TCP mount solves the problem.  I can live with TCP mount,
but I wanted to report the problem to get it fixed.

The network adapter is an Intel one:
    fxp1 at pci2 dev 4 function 0: i82550 Ethernet, rev 13
    fxp1: interrupting at ioapic0 pin 22
    fxp1: Ethernet address 00:02:b3:60:5f:b8

    004:04:0: Intel 82557 Fast Ethernet LAN Controller (ethernet network, 
revision 0x0d)

There is nothing like gigE or jumbo frames enabled:
fxp1: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> mtu 1500
        
capabilities=3f00<IP4CSUM_Rx,IP4CSUM_Tx,TCP4CSUM_Rx,TCP4CSUM_Tx,UDP4CSUM_Rx,UDP4CSUM_Tx>
        enabled=0
        address: 00:02:b3:60:5f:b8
        media: Ethernet autoselect (100baseTX 
full-duplex,flowcontrol,rxpause,txpause)
        status: active
        inet 192.168.1.1 netmask 0xffffff00 broadcast 192.168.1.255
        inet6 fe80::202:b3ff:fe60:5fb8%fxp1 prefixlen 64 scopeid 0x2
