many small packets.

I have on-board 1GiG network card:
em0 at pci0:0:25:0: class=0x020000 card=0x82681043 chip=0x10bd8086
rev=0x02 hdr=0x00
vendor = 'Intel Corporation'
device = '82566DM-2 Gigabit Network Connection'
class = network
subclass = ethernet
I have jumboframes enabled:
em0: flags=8843<UP,BROADCAST,RUNNING,SIMPLEX,MULTICAST> metric 0 mtu 9014
It works perfectly on large voulme transfers: copy 8GiB file va NFS
or SMB works Ok in both direction.
But when I try to run `kdeinit4' on this computer with DISPLAY points
to other computer (my desktop), I get 2-3:
em0: watchdog timeout -- resetting
em0: link state changed to DOWN
em0: link state changed to UP
I found, that some chips should be reflashed with new EEPROM, but not
this one.
Is here any solution?
