Hello Maxime, Luca,

Commit 471350f6cd ("net/mlx5: prepend implicit items in sync flow 
creation") on 24.11 regresses eSwitch HWS when representor matching is 
disabled (repr_matching_en=0): traffic that should hit PF NIC Rx rules 
after FDB transfer is no longer received.

The backport dropped the priv->sh->config.repr_matching checks that 
previously gated implicit REPRESENTED_PORT / REG_C_0 prepending. That is 
correct on upstream main after repr_matching_en was removed 
(c41f621786), but on 24.11 the option still exists and, when off, TX 
representor tagging is not set up. Unconditionally prepending those 
matches then scopes NIC rules incorrectly.

Dariusz volunteered to send a fix.

We will send our full report soon.

Regards,
Ali
