Subject: [PATCH net-next] net: lan966x: allow offloading timestamp operations to the PHY
Date: Mon, 7 Mar 2022 10:46:32 +0100 [thread overview]
Message-ID: <20220307094632.3764266-1-horatiu.vultur@microchip.com> (raw)
In case the MAC is using 'netif_rx()' to deliver the skb up the network
stack, it needs to check whether 'skb_defer_rx_timestmap()' is necessary
or not. In case is needed then don't call 'netif_rx()'
