My network driver crashes quickly after loaded. I am wondering why. Maybe
related to my gld_send function, but I do not know why it crashes in system

I don't understand what you mean by 'gld_start is called again'. To me
it looks like you have a bug somewhere in the neighbourhood of either
your gldm_reset() or gldm_start() entry point and you've hit it twice
(hence the two identical stack traces).
A $c in kmdb will give more info. i.e. the function arguments and then
you could use ::print to start deciphering the data structures. It's
not that hard now that the source code is publicly available :-)
Can some one give me some hint?

^^^^ This looks suspicious.
I'd say you had some uninitialized data structure somewhere. Have you
initilized your GLD private data pointer properly?
