[Asterisk-Dev] EAGAIN rtp.c

Under unix and bsd EAGAIN simply means someone set the socket to
non-blocking and proceeded to read the socket before any data arrived.

Here the code is treating EAGAIN as if it were some error.  Is this a
linux thing that I need to note or is it a bug?


	res = recvfrom(rtp->rtcp->s, rtcpdata, sizeof(rtcpdata),
					0, (struct sockaddr *)&sin, &len);
	if (res < 0) {
		if (errno == EAGAIN)
			ast_log(LOG_NOTICE, "RTP: Received packet with bad UDP checksum\n");
			ast_log(LOG_WARNING, "RTP Read error: %s\n", strerror(errno));
		if (errno == EBADF)
		return &null_frame;
