From: Dima Chumak <dchumak@xxxxxxxxxx> commit 55b2ca702cfa744a9eb108915996a2294da47e71 upstream. 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.
