Squashed commit of the following: net/tcp: Add logic to send probes when SO_KEEPALIVE is enabled. net/tcp: TCP socket should not have to be connected to configure KeepAlive. net/: Add a separate configuration to enable/disable KEEPALIVE socket options. net/tcp: Arguments to TCP keep-alive timing functions probably should be struct timeval as are the times for other time-related socket options. net/tcp: Fix a backward conditional net/tcp: Add some more checks and debug output to TCP-protocol socket options. net/tcp: Cosmetic changes to some alignment. net/: Adds socket options needed to manage TCP-keepalive and TCP state machine logic to detect if that the remote peer is alive. Still missing the timer poll logic to send the keep-alive probes and the state machine logic to respond to probes. 2018-03-12 17:59:46 +01:00			`config NET_TCPPROTO_OPTIONS`
