Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-01-22 This series contains updates to e1000, e1000e, igb, fm10k and virtio_net. Asaf Vertz provides a fix for e1000 to future-proof the time comparisons by using time_after_eq() instead of plain math. Mathias Koehrer provides a fix for e1000e to add a check to e1000_xmit_frame() to ensure a work queue will not be scheduled that has not been initialized. Jacob adds the use of software timestamping via the virtio_net driver. Alex Duyck cleans up page reuse code in igb and fm10k. Cleans up the page reuse code from getting into a state where all the workarounds needed are in place as well as cleaning up oversights, such as using __free_pages instead of put_page to drop a locally allocated page. Richard Cochran provides 4 patches for igb dealing with time sync. First provides a helper function since the code that handles the time sync interrupt is repeated in three different places. Then serializes the access to the time sync interrupt since the registers may be manipulated from different contexts. Enables the use of i210 device interrupt to generate an internal PPS event for adjusting the kernel system time. The i210 device offers a number of special PTP hardware clock features on the Software Defined Pins (SDPs), so added support for two of the possible functions (time stamping external events and periodic output signals). Or Gerlitz fixes fm10k from double setting of NETIF_F_SG since the networking core does it for the driver during registration time. Joe Stringer adds support for up to 104 bytes of inner+outer headers in fm10k and adds an initial check to fail encapsulation offload if these are too large. Matthew increases the timeout for the data path reset based on feedback from the hardware team, since 100us is too short of a time to wait for the data path reset to complete. Alexander Graf provides a fix for igb to indicate failure on VF reset for an empty MAC address, to mirror the behavior of ixgbe. Florian Westphal updates e1000 and e1000e to support txtd update delay via xmit_more, this way we won't update the Tx tail descriptor if the queue has not been stopped and we know at least one more skb will be sent right away. ==================== Signed-off-by: -

Tom Herbert says: ==================== vxlan: Don't use UDP socket for transmit UDP socket is not pertinent to transmit for UDP tunnels, checksum enablement can be done without a socket. This patch set eliminates reference to a socket in udp_tunnel_xmit functions and in VXLAN transmit. Also, make GBP, RCO, can CSUM6_RX flags visible to receive socket and only match these for shareable socket. v2: Fix geneve to call udp_tunnel_xmit with good arguments. ==================== Signed-off-by: -

In the vxlan transmit path there is no need to reference the socket for a tunnel which is needed for the receive side. We do, however, need the vxlan_dev flags. This patch eliminate references to the socket in the transmit path, and changes VXLAN_F_UNSHAREABLE to be VXLAN_F_RCV_FLAGS. This mask is used to store the flags applicable to receive (GBP, CSUM6_RX, and REMCSUM_RX) in the vxlan_sock flags. Signed-off-by:

The UDP tunnel transmit functions udp_tunnel_xmit_skb and udp_tunnel6_xmit_skb include a socket argument. The socket being passed to the functions (from VXLAN) is a UDP created for receive side. The only thing that the socket is used for in the transmit functions is to get the setting for checksum (enabled or zero). This patch removes the argument and and adds a nocheck argument for checksum setting. This eliminates the unnecessary dependency on a UDP socket for UDP tunnel transmit. Signed-off-by:

Sathya Perla says: ==================== be2net: patch set Hi David, as the below patch-set includes minor bug fixes and some code re-org, pls consider applying it to the "net-next" tree. Thanks! Patch 1 fixes a bit of code duplication involving interface object creation code. Patch 2 ensures that when a flow-control FW cmd fails, the adapter state continues to reflect the old values. This allows for correct reporting on subsequent ethtool "get". Patch 3 returns proper error for link config change on BE3/Lancer Patch 4 adds a kernel log message for FW boot error on Lancer Patch 5 adds a function reset on Lancer as a part of the function init sequence. Patch 6 moves some FW-cmd definitions that belong in be_cmds.h, but were placed in be_hw.h Patch 7 resets the "bw_min" field while configuring "bw_max" needed for TX rate limiting config. ==================== Signed-off-by: -

Romain Perier says: ==================== net: stmmac: dwmac-rk: Fix phy regulator issues This series fixes few issues in dwmac-rk: 1. Voltage settings was hardcoded into the driver for the phy regulator. The driver now uses the default voltage settings found in the devicetree, which are applied throught the regulator framework. 2. The regulator name used to power on or power off the phy was put in the devicetree variable "phy_regulator", which is not standard and added a lot of code for nothing. The driver now uses the devicetree property "phy-supply" and the corresponding functions to manipulate this regulator. The corresponding devicetree files are also updated. As this new binding for rk3288 has not been released with any official kernel yet (not until 3.20), I don't need to care about keeping compatibility with the old non standard property. ==================== Tested-by:

Currently, dwmac-rk uses a custom propety "phy_regulator" to get the name of the right regulator to use to power on or power off the phy. This commit converts the driver to use phy-supply devicetree property and the corresponding API, it cleans the code a bit and make it simpler to maintain. This also replaces the property phy_regulator by the standard property phy-supply in rk3288-evb-rk808.dts. Signed-off-by:

As these settings can be directly expressed from devicetree for both fixed regulators and pmic-integrated regulators, it is more standard to set them from dts and let the regulator framework use the right voltage informations when it is used in the driver. Signed-off-by:

Always fully coalesce guest Rx packets into the minimum number of ring slots. Reducing the number of slots per packet has significant performance benefits when receiving off-host traffic. Results from XenServer's performance benchmarks: Baseline Full coalesce Interhost VM receive 7.2 Gb/s 11 Gb/s Interhost aggregate 24 Gb/s 24 Gb/s Intrahost single stream 14 Gb/s 14 Gb/s Intrahost aggregate 34 Gb/s 34 Gb/s However, this can increase the number of grant ops per packet which decreases performance of backend (dom0) to VM traffic (by ~10%) /unless/ grant copy has been optimized for adjacent ops with the same source or destination (see "grant-table: defer releasing pages acquired in a grant copy"[1] expected in Xen 4.6).
