Thanks 28/10/2025 10:52, a.schollmeyer@syseleven.de: > From: Adrian Schollmeyer > > For shared Rx queues, equal MTU for all ports sharing queues is enforced > using mlx5_shared_rxq_match() to make sure, the memory allocated in the > Rx buffer is large enough. The check uses the MTU as reported by the > ports' private dev_data structs, which contain the MTU currently set for > the device. In case one port's MTU is altered after Rx queues are > allocated and then a second port joins the shared Rx queue with the old, > yet correct MTU, the check fails despite the fact that the Rx buffer > size is correct for both ports. > > This patch adds a new entry to the Rx queue control structure that > captures the MTU at the time the Rx buffer was allocated, since this is > the relevant information that needs to be checked when a port joins a > shared Rx queue. > > Fixes: 09c2555303be
