  Max frame size is not set to HW, so packets above the MTU
do not get dropped by HW. The patch fixed the issue.

Hi,

Could you provide the Fixes tag and cc stable?

Thanks,

It's a persistent issue,  maybe  it is an implementation miss.
So  Fixes tag can't be provided.  Like this,  need cc stable?

If it is an implementation miss since the driver was written then please
set the Fixes tag to the commit where the driver was introduced.

I think in this case, the fix tag could be the first commit that introduced
icd driver.
