have not heard of such feature available, but technically, the reason why serial port is important is because it is initialized at a very early stage in linux kernel bootup, and anything that happened before that cannot be analyzed via kgdb as well. i am not sure why u need ethernet. normally my approach is to use VirtualBox running a kernel with kgdb parameters all setup, and then define a virtual serial port in VirtualBox, to connect to a pipe, and then from host OS, use gdb to attach via "target remote" to the virtual terminal, which is created via the "socat" command.
