- Test Steps:

- 2. Set channel_accept callback for NUT's meshlink_set_channel_accept_cb API.
- 3. Export and Import nodes.
- 4. Open a channel with NUT from bar to invoke channel accept callback
- 5. Open a channel with bar from NUT to invoke channel accept callback
-
- Expected Result:
- Opens a channel by invoking accept callback, when accept callback rejects the channel
- it should invoke the other node's receive callback with length = 0 and no error.
