Works really nice now. 20 usecs base period => 50 kHz, 25 kHz pulse freq.

I works.

Use 4.19-rt kernel
Ethernet Intel I210 controller
ethtool -C enp1s0 rx-usecs 0 tx-usecs 0
2 ms loop time in linuxcnc .ini and .xml and code
baseTimer period can be adjusted
startTime for baseTimer can also be adjusted.

Stepgen3 is driven by HardwareTimer, in a way that resembles EtherCAT setup. Seems to actually work.

Well it works, network-wise. But there are those extra peaks that have been since the start. Let's see if I can remove them. Welcome StepGen3

It works. I hate RealTek. Even with the r8618_dkms driver it doesn't work. I bought a Intel network card, set irq coalesce rx-usecs and tx-usecs to 0. Now it works works WORKS. No lost packages, no delayed packages. I hate RealTek

Yes it works now. Made another implementation of the pulse IRQ and all that. We'll see if I keep this or go back to the older. It is IMPORTANT, REQUIRED to use a 4.9 linux kernel for it to work. There are obviously bugs in the RealTek network drivers R8168/R8169 in 5+ kernels. All this work could have been avoided with a 4.9 kernel.
