Hi Gerhard,

I think it would be nice to find a way forwards that resolved
the regression without reverting the feature. But, if that doesn't work
out, I think the following two patches need to be reverted first in
order to avoid breaking (x86_64 allmodconfig) builds.

 352e9bf23813 ("ice: enable symmetric-xor RSS for Toeplitz hash function")
 4a3de3fb0eb6 ("iavf: enable symmetric-xor RSS for Toeplitz hash function")
