From ac52caa31e0a135a8940a66de763751760820f37 Mon Sep 17 00:00:00 2001 From: =?utf8?q?Micha=C5=82=20Miros=C5=82aw?= Date: Wed, 8 Jun 2011 08:38:01 +0000 Subject: [PATCH] igb: convert to ndo_fix_features MIME-Version: 1.0 Content-Type: text/plain; charset=utf8 Content-Transfer-Encoding: 8bit Private rx_csum flags are now duplicate of netdev->features & NETIF_F_RXCSUM. Removing this needs deeper surgery. Things noticed: - HW VLAN acceleration probably can be toggled, but it's left as is - the resets on RX csum offload change can probably be avoided - there is A LOT of copy-and-pasted code here Signed-off-by: Michał Mirosław Tested-by: Aaron Brown Signed-off-by: Jeff Kirsher --- drivers/net/igb/igb_ethtool.c | 67 ------------------------------------------- drivers/net/igb/igb_main.c | 33 ++++++++++++++++----- 2 files changed, 26 insertions(+), 74 deletions(-) diff --git a/drivers/net/igb/igb_ethtool.c b/drivers/net/igb/igb_ethtool.c index fdc895e..1862c97 100644 --- a/drivers/net/igb/igb_ethtool.c +++ b/drivers/net/igb/igb_ethtool.c @@ -318,65 +318,6 @@ static int igb_set_pauseparam(struct net_device *netdev, return retval; } -static u32 igb_get_rx_csum(struct net_device *netdev) -{ - struct igb_adapter *adapter = netdev_priv(netdev); - return !!(adapter->rx_ring[0]->flags & IGB_RING_FLAG_RX_CSUM); -} - -static int igb_set_rx_csum(struct net_device *netdev, u32 data) -{ - struct igb_adapter *adapter = netdev_priv(netdev); - int i; - - for (i = 0; i < adapter->num_rx_queues; i++) { - if (data) - adapter->rx_ring[i]->flags |= IGB_RING_FLAG_RX_CSUM; - else - adapter->rx_ring[i]->flags &= ~IGB_RING_FLAG_RX_CSUM; - } - - return 0; -} - -static u32 igb_get_tx_csum(struct net_device *netdev) -{ - return (netdev->features & NETIF_F_IP_CSUM) != 0; -} - -static int igb_set_tx_csum(struct net_device *netdev, u32 data) -{ - struct igb_adapter *adapter = netdev_priv(netdev); - - if (data) { - netdev->features |= (NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM); - if (adapter->hw.mac.type >= e1000_82576) - netdev->features |= NETIF_F_SCTP_CSUM; - } else { - netdev->features &= ~(NETIF_F_IP_CSUM | NETIF_F_IPV6_CSUM | - NETIF_F_SCTP_CSUM); - } - - return 0; -} - -static int igb_set_tso(struct net_device *netdev, u32 data) -{ - struct igb_adapter *adapter = netdev_priv(netdev); - - if (data) { - netdev->features |= NETIF_F_TSO; - netdev->features |= NETIF_F_TSO6; - } else { - netdev->features &= ~NETIF_F_TSO; - netdev->features &= ~NETIF_F_TSO6; - } - - dev_info(&adapter->pdev->dev, "TSO is %s\n", - data ?
