Hello,
When we use cassini driver without VLANs, it works as expected but when
about 100 VLANs are configured on this interface, the hardware checksum
fails.
What is its reason or how can we debug it?

I tried it that I "disable" the checksum on the hardver side, in fact, I
used CHECKSUM_NONE instead of CHECKSUM_HW but in this case the driver
allocated all available memory after receiving a few hundred MiB data.
