--nextPart1429025.e96ZJUYYFQ Content-Type: text/plain; charset="us-ascii" Content-Transfer-Encoding: quoted-printable Content-Disposition: inline After recently updating the windows drivers (I dual-boot Windows XP on the= =20 machine the NIC is in), I hit this problem:=20 http://gentoo-wiki.com/HARDWARE_RTL8168#Troubleshooting which affects re(4)= =20 like it does the Linux drivers described in the above link.=20 I already wrote the Realtek technical support about it since their "own"=20 =46reeBSD driver (a hacked rl(4) that does not support any of the chip's=20 advanced features) does not manage to power up the PHY on its own either -= =20 neither does the motherboard's BIOS when trying to netboot. The other problem is that I have at least two applications misbehaving when= =20 rxcsum/txcsum is enabled:=20 =2D The Linux Second Life client (yes, yes, I know, but it is nice for show= ing=20 off GLX and it is really really good at generating network traffic) will=20 cease to receive data after about a minute or so - turning off rcxsum/txcsu= m=20 will mend it on the spot. =2D A Fedora Core 4 running in Qemu, networked with bridge(4) and tap(4), c= annot=20 receive an ip address via DHCP. Interestingly, this even occurs if=20 rxcsum/txcsum was already turned off before launching Qemu - to make it wor= k,=20 I have to cycle rxcsum/txcsum once. Might be related to promiscuous mode. I realise that both of these make awful test cases, but so far they are the= =20 only applications I found to expose those problems.
