Change RTCS MTU

Mike_d — Thu, 06 Jul 2017 23:14:37 GMT

Hi,

I have a wifi interface that has an MTU less than 1500. How do I change the MTU for RTCS?

Thanks,

-Mike

Hi Mike_d

This MTU is defined in the following macro

#define ENET_FRAMESIZE_MAXDATA (1500)

in file

mqx/source/io/enet/ethernet.h

Have a great day,
Daniel

Hi Mike_d

There is also a similar macro in RTCS IP layer.

#define IP_DEFAULT_MTU     576      /* minimum IP datagram size which    */
                                    /* must be supported by all IP hosts */
#define IP_MAX_MTU         0xFFFF   /* size of largest IP datagram       */

in rtcs/source/include/ip.h

Regards

Daniel
