66ef6d143a This commit adds an initial implemented of TCP delayed ACKs as specified in RFC 1122.
Squashed commit of the following:

    net/tmp:  Rename the unacked field of the tcp connection structure to tx_unacked.  Too confusing with the implementation of delayed RX ACKs.

    net/tcp:  Initial implementation of TCP delayed ACKs.

    net/tcp:  Add delayed ACK configuration selection.  Rename tcp_ack() to tcp_synack().  It may or may not send a ACK.  It will always send SYN or SYN/ACK.

9efadaefc1 net/tcp: Be consistent with units of TIME_WAIT. Units were unspecified in tcp/Kconfig, but assumed to be in units of half seconds in tcp/timer.h. include/nuttx/netconfig does not indicate the units but is apparently assuming seconds. This commit unifies all delays to clearly specified units of seconds. 2019-11-24 09:19:54 -06:00

ae399b9b62 net/tcp: In tcp_input(), add the logic to detect, decode, and respond to TCP Keep-Alive packets. In tcp_timer(), fix some problems with the way that TCP Keep-Alive probes were being formatted. 2018-03-12 15:54:45 -06:00

251924a734 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.
