I have an ethernet card with a Realtek 8139C chip , and I've enabled IPv6 in my kernel (2.4.23)
My ethernet card is connected to an ADSL Modem , an Ericsson HM220dp, and every (appoximatly) 50000 packets transmitted/recived by the devices ,if IPv6 is enabled , ifconfig reports an error in RX packages :
bash-2.05b# ifconfig
eth0 Link encap:Ethernet HWaddr 00:E0:7D:D5:0C:ED
inet6 addr: fe80::2e0:7dff:fed5:ced/64 Scope:Link

Interrupt:17 Base address:0x5f00The modem is connected at 10Mbps speed Half-Duplex .
If I disable IPv6 I don't see errors on the ethernet device , I've tried until 1500000 packets without errors .
What cause those errors? The only solution is disable IPv6?? I've found this problem on 2.4.22 too (I haven't tried IPv6 on previous kernels)
Thanks
