Turn off the problematic hardware flow offloading on MT7621.

For solve your problems, you just discard problems?

Hi @MeIsReallyBa , which kernel version is suitable for this patch?

Hi @MeIsReallyBa! Why not issue a pull request?

I have used hardware offload for a long time,no problem here.

It's possible issue a pull request and request testers. "RFT" -> pull request ready for testing

There is no "hardware offload" option available applying this patch ?

There should be hardware flow offload option in firewall setting even if u didn't apply this patch.

This option depends on your actual MT7621 device ?

I do not have tried stock rc3 and re-built again

Model Ubiquiti EdgeRouter X

Hardware offload option will appear when you select software flow offload first.

I tried to build at branch 21.02 with commit https://github.com/openwrt/openwrt/commit/b55d3d69044ae872c96b4b287b43a57c8e96e7cd , but I cannot represent a nearly 0% usage of CPU like yours. Device is MikroTik Rb750Gr3. Can we talk about this deeper?
