Problem with re0

[Zeus V Panchenko]

Hi all,

the same problem i wrote in the first posts about year ago :(

onboard re(4) tremendous flapping

while ( cable connects nic and switch )
{
 re0: link state changed to UP
 re0: link state changed to DOWN
}


here the details:

re0 at pci0:2:0:0: class=0x020000 card=0x83a31043 chip=0x816810ec rev=0x03 hdr=0x00
    vendor     = 'Realtek Semiconductor'
    device     = 'Gigabit Ethernet NIC(NDIS 6.0) (RTL8168/8111/8111c)'
    class      = network
    subclass   = ethernet


flapping starts with cable pluging to the nic and to the switch, even without ip assignment
switch used is TP-LINK TL-SG5426


the problem persists already about year and the only solution is to use external nic ...

any idea/news?
