Fedora and other distros with recent kernels already have it.
I guess there is some significant demand for it from Mikrotik's customers. I'll probably use it.
MikroTik users don't have it in stable RouterOS releases either. This is a development ("beta") release for testing purposes.

Try loading (or recompiling) kernel modules. It’s a different story there, as they have no issues breaking that between releases.
This goes the other way around a well, they often cherry-pick new code and pull it back into their curated kernels to support the latest hardware offerings of their partners (Dell, HP, Broadcom, etc.) without pulling in possible unstable newer kernel code around it; they have contractors from those hardware companies assisting in the work to backport hardware module features.
Maybe Pera will get hit by a bus and things will get turned around but otherwise it's a sad mess and waste of potential.
I haven't updated/tested in awhile but last I remember I was seeing 800+ mbit/s on my dinky mips ER-X. Pretty amazing and easy to use.
Development of EdgeOS has really slowed down though, there hasnt been a stable firmware update in 6 months (and that was just a small hotfix).
Why would one want that workload on their router when they can offload it to a $35 Pi?
Of course, benchmarks from random strangers are not gospel, and the results aren’t particularly damning. But even then, you’re assuming that you have the luxury of running on a chip that comes with a hardware crypto engine. Good luck trying to get AES encryption/decryption speeds at anywhere near line rate with a Raspberry Pi or a run-of-the-mill router.
For ROS7, however, support said in June:
That is not yet readily available since v7 is not really complete yet and is during heavy development right now, everything is changing, including the kernel. I will inquire how long it will take to get the files you need and will let you know once I have some information.

I have two and just got them working and haven't updated in maybe a year. I use them as internal switches and only really use vlans + dhcp.
It might be interesting to see if porting is a big deal. I have one annoying weirdness where ports are labeled sfp,1-5,6-10, but the logical mapping is really screwed up switch0:6, switch0:1,2,3,4,5, then switch1:5,4,3,2,1 (reversed)
The Marvell switch chip supports IPv6 but for now Mikrotik only implemented support for v4 offload.. :/
