Hi Dave,
Thanks for this work. I think this functionality is going to have many uses!
One question: is there a good reason why the ULP infrastructure should
just be for TCP sockets. For example, I'd really like to be able
something like:
setsockopt(sock, SOL_SOCKET, SO_ULP, &ulp_param, sizeof(ulp_param));
Where ulp_param is a structure containing the ULP name as well as some
ULP specific parameters that are passed to init_ulp. ulp_init could
determine whether the socket family is appropriate for the ULP being
requested.
Thanks,
Tom
