@bjsowa check failing test regarding the Eclipse ECA. Otherwise, we will not be able to merge this PR.

Do you have a timeline for the remaining features?

Fixed

Do you have a timeline for the remaining features?

I don't.

A first quick review.
Tests must be also provided...at least build tests.

+        ret = _Z_ERR_GENERIC;
+    }
+
+    ep->_iptcp->ai_addr->sin_family = FREERTOS_AF_INET4;


isn't this value set by getaddrinfo?

Unfortunately not, getaddrinfo only sets ai_family but does not write it to ai_addr->sin_family. I changed it so it at least uses the value returned by getaddrinfo.

+
+unsigned long z_clock_elapsed_s(z_clock_t *instant) { return z_time_elapsed_ms(instant) * 1000; }


This will return seconds but useconds instead.

Fixed it. It is worth noting that the emscripten port, which I used for reference, has the same issue.

@cguimaraes I added TCP support, some examples and CI workflow. Could you review the changes?

The examples use POSIX port of FreeRTOS and network interface implementation that uses SLiRP library to emulate a userspace NAT network. I was able to use the examples on Linux in client mode with a Zenoh Router running on the host. Peer mode won't work as this port does not support incoming connections.

@cguimaraes I added Multi threading support and extended Zenoh-pico API to allow passing port-specific task attributes when creating read and lease tasks (example usage in z_pub.c). Let me know what you think about it.

Multicast is not fully supported in FreeRTOS-Plus-TCP (see FreeRTOS/FreeRTOS-Plus-TCP#962) so I'll have to pass on UDP Multicast for now. I'll also pass on IPv6 support as I don't need it.

I'll mark this PR as Ready for review once I'll have it tested on a microcontroller.

@bjsowa I've just realised that this PR is still open. In the meanwhile we have released zenoh 0.10.0 and it seems there are some conflicts to be resolved before merging.
