Support of Intel i225 TAPRIO Offload Feature

[rezabfil-sec]

Hello,

We are considering using isochron for our evaluations and I am wondering if it also supports the TAPRIO in HW offload (flags 0x2 https://man7.org/linux/man-pages/man8/tc-taprio.8.html) for these scenarios:

1. running isochron in simple Point-to-Point topology
2. Running isochron for more than P2P where the next hop is also a Linux machine equipped with Intel i225.

Option 1. should be pretty straightforward based on the docs, but I am unsure about the second option. If I understand the flags 0x2, the application has to specify txtime itself and then pass it to the NIC. That would mean that isochron would need to receive the packet and also handle its forwarding on each additional hop. Am I correct?

Thanks for your time and clarifications!
