Hi all, I woulld like to understand if the behaviour i'm getting is correct. When I configure the XDP_UMEM_REG in zerocopy mode with a headroom == 0 on a i40e, the driver (i guess) actually sets a headroom of 256. if i set a headroom == 256 the driver sets a headroom of 512. If this behaviour is correct, would be nice that the xdp_umem_reg struct after the setsockopt call would contain the actual configured headroom. Thank you for your time
