2014-09-28mlx4: exploit skb->xmit_more to conditionally send doorbellEric Dumazet1-7/+16
skb->xmit_more tells us if another skb is coming next. We need to send doorbell when : xmit_more is not set, or txqueue is stopped (preventing next skb to come immediately) Tested with a modified pktgen version, I got a 40% increase of throughput.

2014-09-28net: dsa: bcm_sf2: add port_enable/disable callbacksFlorian Fainelli1-20/+40
The SF2 switch driver is already architected around per-port enable/disable callbacks, so we just need a slight update to our existing bcm_sf2_port_setup() resp. bcm_sf2_port_disable() functions to be suitable as callbacks for port_enable/port_disable.

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-09-23 This patch series adds support for the FM10000 Ethernet switch host interface. The Intel FM10000 Ethernet Switch is a 48-port Ethernet switch supporting both Ethernet ports and PCI Express host interfaces. The fm10k driver provides support for the host interface portion of the switch, both PF and VF. As the host interfaces are directly connected to the switch this results in some significant differences versus a standard network driver. For example there is no PHY or MII on the device. Since packets are delivered directly from the switch to the host interface these are unnecessary. Otherwise most of the functionality is very similar to our other network drivers such as ixgbe or igb. For example we support all the standard network offloads, jumbo frames, SR-IOV (64 VFS), PTP, and some VXLAN and NVGRE offloads. v2: converted dev_consume_skb_any() to dev_kfree_skb_any() fix up PTP code based on feedback from the community v3: converted the use of smb_mb__before_clear_bit() to smb_mb__before_atomic() added vmalloc header to patch 15 added prefetch header to patch 16 ==================== Signed-off-by: David S.

It's overriding code which does exactly the same thing. Actually, more precisely, this code is duplicating code in a way that bypasses many core facilitites of the networking. For example, this override means that socket based flow steering, XPS, etc. are all not happening on these devices.

If the system does not have a CCP this will result in -ENODEV being returned whenever a command is attempted to be queued by the registered crypto algorithms.

2014-09-23fm10k: Add support for PTPAlexander Duyck7-1/+683
This change adds support for the Linux PTP Hardware clock and timestamping functionality provided by the hardware. There are actually two cases that this timestamping is meant to support. The first case would be an ordinary clock scenario. In this configuration the host interface does not have access to BAR 4. However all of the host interfaces should be locked into the same boundary clock region and as such they are all on the same clock anyway. With this being the case they can synchronize among themselves and only need to adjust the offset since they are all on the same clock with the same frequency. The second case is a boundary clock scenario. This is a special case and would require both BAR 4 access, and a means of presenting a netdev per boundary region. The current plan is to use DSA at some point in the future to provide these interfaces, but the DSA portion is still under development.

In the case of Tx timestamps it is necessary for the Switch Management entity to return the frames via the mailbox as the host interface cannot know which port the timestamp will be delivered to. In addition there is only one clock on the entire switch, as such the entity that has BAR 4 access is the only one who can actually update the frequency as it is the only one with access.

This patch adds limited debugfs support for the driver. Most of the functionality needed for dumping registers is already provided via ethtool. The only thing we saw that we really neeed was the ability to dump the descriptor rings so as such this patch will add a fm10k directory containing a listing of directories each one with a unique PCI Bus, Device, and Function number. Each of those BDF directories will have a list of q_vectors, and the q_vectors will contain a file for each of the Rx/Tx rings that are a part of the vector. For example: # ls -RD /sys/kernel/debug/fm10k/ /sys/kernel/debug/fm10k/: 0000:01:00.0 /sys/kernel/debug/fm10k/0000:01:00.0: q_vector.000 q_vector.001 q_vector.002 q_vector.003 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000: rx_ring.000 tx_ring.000 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.001: rx_ring.001 tx_ring.001 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.002: rx_ring.002 tx_ring.002 /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.003: rx_ring.003 tx_ring.003 # cat /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000/rx_ring.000 DES DATA RSS STATERR LENGTH VLAN DGLORT SGLORT TIMESTAMP --------------------------------------------------------------------------- 000 0x00000000 0x00000000 0x00000003 0x002a 0x0000 0x0000 0x0000 0x13951807dc4fedf0 001 0x00000000 0x00000000 0x00000003 0x002a 0x0000 0x0000 0x0000 0x1395180906c9f2c8 002 0x3731c000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 003 0x3731d000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 004 0xaab3a000 0x00000000 0x00000000 0x0000 0x0000 0x0000 0x0000 0x0000000000000000 ... # cat /sys/kernel/debug/fm10k/0000:01:00.0/q_vector.000/tx_ring.000 DES BUFFER_ADDRESS LENGTH VLAN MSS HDRLEN FLAGS --------------------------------------------------------- 000 0x00000000aa8a1002 0x005a 0x0000 0x0000 0x0000 0xc0 001 0x00000000aa8a2002 0x005a 0x0000 0x0000 0x0000 0xc0 002 0x000000006bc13202 0x004e 0x0000 0x0000 0x0000 0xc0 003 0x000000006bc13c02 0x002a 0x0000 0x0000 0x0000 0xe1 004 0x000000006bc13602 0x0062 0x0000 0x0000 0x0000 0xc0 Signed-off-by: Alexander Duyck <alexander.h.duyck@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com>
2014-09-23fm10k: Add support for IEEE DCBxAlexander Duyck4-4/+185
This patch adds support for management of the limited QOS features of the FM10000 interface. Specifically we can support up to 8 traffic classes, however the part only provides 1 Rx and 1 Tx FIFO in the host interface and as a result this can lead to head-of-line blocking on Rx. This can be avoided by setting PFC only for priorities that cannot afford to drop frames.

2014-09-23fm10k: Add support for SR-IOV to driverAlexander Duyck5-2/+614

2014-09-23fm10k: Add support for PF <-> VF mailboxAlexander Duyck2-0/+834
This patch adds support for the PF <-> VF mailbox. It functions similar to the PF <-> SM mailbox however there are several modifications made to improve the reliability of the mailbox itself. In addition the PF/VF mailbox is much smaller an only supports a total size of 16 DWORDs vs the 1024 DWORDS provided for the PF/SM mailbox.

2014-09-23fm10k: Add support for MACVLAN accelerationAlexander Duyck4-1/+198
This patch adds support for L2 MACVLAN by making use of the fact that the RRC provides a unique tag per filter called a Global Resource Tag, or GLORT. In the case of this offload what I have done is assigned a linear block of these so that each GLORT represents one of the MACVLAN netdevs. By doing this I can share the Rx queues and Tx queues for all of the MACVLAN netdevs while allowing them to be demuxed in the Rx cleanup path.

2014-09-23fm10k: Add support for netdev offloadsAlexander Duyck2-3/+459

2014-09-23fm10k: Add support for multiple queuesAlexander Duyck4-0/+247
This patch takes the driver from supporting a single queue to supporting multiple queues. The upper queue limit for the PF is 128 queues and the upper limit for the VF is (128 / num_vfs) rounded down to nearest power of 2.
