RTL8111/8168B PCI Express Gigabit Ethernet controller" to receive multicast packets? I am developing a piece of software to receive a multicast signal as produced by the mp4live program in the mpeg4ip project. The software has worked on a wide variety of hardware until I got to this one machine with the above realtek chip. I noticed it was unable to connect to the stream. I was never able to get it to properly receive the signal until I put in a new NIC, a "3Com Corporation 3c905C-TX/TX-M" and now the program is once again receiving multicast packets. So I believe the realtek driver is possibly not doing something correctly. Are there any known issues with my hardware? Is there anything I could do from a kernel space or user space level that would further help diagnose the problem? My OS is an up to date Fedora with all fedora packages except the piece of software I am developing. Thanks, Jon
