[BPI-R4] hardware flow-offloading with 4 GiB of RAM

Banana Pi Router design BPI-R4(MT7988)

Hi,

I have seen this mentioned “hardware flow-offloading if using all 4 GiB of RAM right now it only works with mem=2048M appended to kernel cmdline)”

Is anyone able to explain this a bit more, why is it? Can we work around it somehow with some device tree or driver changes?

Is there is still a problem with HW offloading.

I cannot connect to anything when I enable HW offloading, it works with SW offloading or no offloading at all enable in the firewall part.

It works on latest openwrt snapshot.
