Should be ok, if the destination adress is our address or a broadcast one.

By default, the server socket is configured to send data as soon as possible, without delay (TCP_NODELAY ). You can try to play with its TCP socket options: https://fnet.sourceforge.io/manual/group__fnet__socket_ga989481a2cee0291e70f9076a091eddf1.html#ga989481a2cee0291e70f9076a091eddf1

TCP segmentation it is a feature of TCP ;)

Think about the MCUBoot secondary bootloader. It has security, recovery and differeant FW update modes.

Yes you can.

Thank you for reporting, will look at it when have a time.

Hi, Agree, this is the bug. But do not add fnet_htons(). The right code should be (fnet_stack\service\dns\fnet_dns.c, line 421): && ((header->flags & FNET_HTONS(FNET_DNS_HEADER_FLAGS_QR)) == FNET_HTONS(FNET_DNS_HEADER_FLAGS_QR)) /* Is response.*/ Please confirm, that it works for you. Thank you, Andrej Butok

To have a MCUx example, it must be part of a MCUx SDK package. It is needed to convince NXP to add FNET support to the SDK.
