Pages allocated with GFP_ATOMIC cannot come from Highmem. This is why
there is no need to call kmap() on them.
Therefore, don't call kmap() on rx_buffer->page() and instead use a
plain page_address() to get the kernel address.

I send again this patch because it was submitted more than two months ago,
Monday 4th July 2022, but for one or more (good?) reasons it has not yet
reached Linus' tree. In the meantime I am also forwarding two "Reviewed-by"
and one "Tested-by" tags (thanks a lot to Ira, Alexander, Gurucharan).
Obviously I have not made any changes to the code.
Hi Fabio,
This is accepted into net-next already[1] and will land in the next kernel.
Thanks,
Tony
