Hello:
Is anyone familiar with ipv6? My UDP works well now, but TCP is
not . My computer connects my ecos equipment fail .
This is ipv4 connect : (IPV4 works well.)

This is IPV6 connect :

The "tx total_len" of ipv4 and ipv6 both are 74. I'm not familiar with
TCP/IP but I think They should not be the same. Does anyone hit this
problem before?
