struct net_device trans_start field is a hot spot on SMP and high performance devices, particularly multi queues ones, because every transmitter dirties it. Is main use is tx watchdog and bonding alive checks. But as most devices dont use NETIF_F_LLTX, we have to lock a netdev_queue before calling their ndo_start_xmit(). So it makes sense to move trans_start from net_device to netdev_queue. Its update will occur on a already present (and in exclusive state) cache line, for free. We can do this transition smoothly. An old driver continue to update dev->trans_start, while an updated one updates txq->trans_start. Further patches could also put tx_bytes/tx_packets counters in netdev_queue to avoid dirtying dev->stats (vlan device comes to mind) Signed-off-by:

When using bnx2 in a high transmit load, bnx2_tx_int() cost is pretty high. There are two reasons. One is an expensive call to bnx2_get_hw_tx_cons(bnapi) for each freed skb One is cpu stalls when accessing skb_is_gso(skb) / skb_shinfo(skb)->nr_frags because of two cache line misses. (One to get skb->end/head to compute skb_shinfo(skb), one to get is_gso/nr_frags) This patch : 1) avoids calling bnx2_get_hw_tx_cons(bnapi) too many times. 2) makes bnx2_start_xmit() cache is_gso & nr_frags into sw_tx_bd descriptor. This uses a litle bit more ram (256 longs per device on x86), but helps a lot. 3) uses a prefetch(&skb->end) to speedup dev_kfree_skb(), bringing cache line that will be needed in skb_release_data() result is 5 % bandwidth increase in benchmarks, involving UDP or TCP receive & transmits, when a cpu is dedicated to ksoftirqd for bnx2. bnx2_tx_int going from 3.33 % cpu to 0.5 % cpu in oprofile Note : skb_dma_unmap() still very expensive but this is for another patch, not related to bnx2 (2.9 % of cpu, while it does nothing on x86_32) Signed-off-by:

This patch implements the FCoE Rx side offload feature in ixgbe_main.c to 82599 using the Rx offload infrastructure code added in the previous patch. The large receive offload by Direct Data Placement (DDP) for FCoE is achieved by implementing the ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done in net_device_ops via netdev. It is up to the ULD, i.e., fcoe and libfc to query and setup large receive offload accordingly through the corresponding netdev upon creating fcoe instances. Signed-off-by:

This adds infrastructure code for FCoE Rx side offload feature to 82599, which provides large receive offload for FCoE by Direct Data Placement (DDP). The ixgbe_fcoe_ddp_get() and ixgbe_fcoe_ddp_put() pair corresponds to the netdev support to FCoE by the function pointers provided in net_device_ops as ndo_fcoe_ddp_setup and ndo_fcoe_ddp_done. The implementation of these in ixgbe is shown in the next patch. Signed-off-by:

This patch implements the FCoE Tx side offload features in ixgbe_main.c to 82599 using the Tx offload infrastructure code added in the previous patch. This is achieved by the calling the FCoE Sequence Offload (FSO) function ixgbe_fso() on the transmit path of ixgbe. This patch also includes an EEPROM check to make sure the NIC we're loading on is an offload-enabled SKU. Signed-off-by:

This adds the FCoE feature code ixgbe_fcoe.c to 82599. For a start, this patch only adds ixgbe_configure_fcoe() to configure related register for FCoE to 82599. In patches that follow, I will be adding more functions to ixgbe_fcoe.c to add support of FCoE offload features to 82599. Signed-off-by:

This adds the FCoE feature header ixgbe_fcoe.h to 82599. This header includes the defines and structures required by the ixgbe driver to support various offload features in 82599 for Fiber Channel over Ethernet (FCoE). These offloads features include Fiber Channel CRC calculation, FCoE SOF/EOF auto insertion, FCoE Sequence Offload (FSO) for large send, and Direct Data Placement (DDP) for large receive.

This patch adds three attribute files in /sys/class/net/$dev/ for tun devices; allowing userspace to obtain the information which TUNGETIFF offers, and more, but without having to attach to the device in question (which may not be possible if it's in use). It also fixes a bug which has been present in the TUNGETIFF ioctl since its inception, where it would never set IFF_TUN or IFF_TAP according to the device type. (Look carefully at the code which I remove from tun_get_iff() and how the new tun_flags() helper is subtly different). Signed-off-by:
