Hi,
May I know if this is really an intended fix to post officially, or just
a workaround/probe to make the offset in page_frag happy when
net_high_order_alloc_disable is true? In case it's the former, even
though this could fix the issue, I would assume clamping to a smaller
page_frag than a
Hi, guys, I have a fix patch for this.
Could anybody test it?
Thanks.

Turning out this below commit to unconditionally enable premapped
virtio-net:
commit f9dac92ba9081062a6477ee015bd3b8c5914efc4

value of:
- net.core.high_order_al
Now, we have virtio DMA APIs, the driver can be the premapped
mode whatever the virtio core uses dma api or not.
So remove the limit of checking use_dma_api from
virtqueue_set_dma_premapped().
