net: support being a TCP server to unblock TCP fastboot
Make following changes to unblock TCP fastboot support: 1. Implement being a TCP server support 2. Introduce dedicated TCP traffic handler (get rid of UDP signature) 3. Ensure seq_num and ack_num are respected in net_send_tcp_packet function (make sure existing wget_cmd code is reflected with the fix) Signed-off-by: Dmitrii Merkurev <dimorinny@google.com> Cc: Ying-Chun Liu (PaulLiu) <paul.liu@linaro.org> Cc: Simon Glass <sjg@chromium.org> Сс: Joe Hershberger <joe.hershberger@ni.com> Сс: Ramon Fried <rfried.dev@gmail.com> Reviewed-by: Ying-Chun Liu (PaulLiu) <paul.liu@linaro.org> Reviewed-by: Simon Glass <sjg@chromium.org> Reviewed-by: Ramon Fried <rfried.dev@gmail.com>
