Thanks for adding generic documentation about the files in sysfs.

However, you don't add any specific documentation here about the cxgb4
crash dump. How am i supposed to interpret it? Does it follow any of
the standard core dump formats? How do i use gdb with it? Are there
some specific tools i should use to analyse it?

Thanks
