<pre class="bz_comment_text">With dpdk revision: 24.07.0-rc4, I get the following error when attempting to
create a flow rule using the simple_xor algorithm.

According to the datasheet[1] of the E810 NIC simple_xor is supported.
Had a brief looking into the ice driver, and it seems to have support for
simple_xor.
Both toeplitz and symmetric_toeplitz work correctly.
