sock_addr_testmod provides a mechanism for the sock_addr_kern prog_test to drive socket operations in kernel space. On init, one of the following socket operations is performed based on the module parameters: kernel_bind(), kernel_connect(), or sock_sendmsg()/kernel_sendmsg() and results are exposed through debugfs.

Do we need yet another kernel module? Can this be done as part of existing bpf_testmod module?
