Subject: [PATCH net-next v5 5/9] net: lan966x: Remove .ndo_change_rx_flags
Date:   Wed, 15 Dec 2021 13:13:05 +0100
Message-ID: <20211215121309.3669119-6-horatiu.vultur@microchip.com>

The function lan966x_port_change_rx_flags() was used only when
IFF_PROMISC flag was set. In that case it was setting to copy all the
frames to the CPU instead of removing any RX filters. Therefore remove
it.
