kgdb over ethernet support for 3.x kernel

[Peter Teoh]

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.

Search the web for details.
