Subject: [PATCH net-next 09/11] net: stmmac: dwxgmac2: Also pass control frames while in promisc mode

Sender: linux-kernel-owner@vger.kernel.org
Precedence: bulk

In order for the selftests to run the Flow Control selftest we need to
also pass control frames to the stack.

Pass this type of frames while in promiscuous mode.
