socket raw Eth.

Hello. Who has worked with ETH raw socket on Linux cnc? I'm writing an application running on raw socket, after compiling I run - sudo setcap cap_net_raw+ep NAME.so - Since raw socket requires root, I need to run setcap. Does this break Linux cnc?

Hello everyone. Who has ever worked with socket raw on linux cnc? raw socket requires a set cap, does it break Linux Cnc? I wrote a test driver, on raw socket, receiving data via mmap. As a controller, I use STM32F7 (4 PWM encoders). Maybe I'm doing something wrong, I don't understand the specifics of Mesa, but the first tests show some kind of prohibitive bandwidth, the jitter is lower than on mesa.

We did some tests last year comparing IP network access vs raw packets
with Mesa HostMot2 and the statistical improvement of peak latency  was
minimal so decided it was not worth the effort.

There no issue with root access and LinuxCNC as direct hardware access
requires this and the blocking of normal network traffic on the real time
Ethernet channel also requires root priviledges.
