ldp: return byte count from a successful recvfrom
Unless there's an error, recvfrom should return the number of bytes received. The current code returns zero on success due to ldp_copy_ep_to_sockaddr returning zero. Change-Id: Ib843b99a08c44b5ee2d16efe9edab0cf5df65170 Signed-off-by: Haggai Eran <haggai.eran@gmail.com>
