Re: [Xen-devel] [PATCH net v2 1/3] xen-netback: move NAPI add/remove calls

Originally napi_add was in init_queue and napi_del was in deinit_queue,
while kthreads were handled in _connect and _disconnect. Move napi_add
and napi_remove to _connect and _disconnect so that they reside togother
with kthread operations.
