net/mlx5: Fix offloading with ESWITCH_IPV4_TTL_MODIFY_ENABLE
Only prio 1 is supported for nic mode when there is no ignore flow level support in firmware. But for switchdev mode, which supports fixed number of statically pre-allocated prios, this restriction is not relevant so it can be relaxed. Fixes: d671e109bd85 ("net/mlx5: Fix tc max supported prio for nic mode") Signed-off-by: Dima Chumak <dchumak@nvidia.com> Reviewed-by: Roi Dayan <roid@nvidia.com> Signed-off-by: Saeed Mahameed <saeedm@nvidia.com>
