git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next 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: David S.

2015-01-24vxlan: Eliminate dependency on UDP socket in transmit pathTom Herbert
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: Tom Herbert <therbert@google.com> Signed-off-by: David S.

2015-01-24udp: Do not require sock in udp_tunnel_xmit_skbTom Herbert
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.

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: Heiko Stuebner <heiko@sntech.de> Reviewed-by: Heiko Stuebner <heiko@sntech.de> Signed-off-by: David S.

2015-01-22igb: Indicate failure on vf reset for empty mac addressAlexander Graf
Commit 5ac6f91d changed the igb driver to expose a zero (empty) mac address to the VF on reset rather than a random one. However, that behavioral change also requires igbvf driver changes which can be hard especially when we want to talk to proprietary guest OSs. Looking at the code previous to the commit in Linux that made igbvf work with empty mac addresses (8d56b6d), we can see that on reset failure the driver will try to generate a new mac address with both the old and the new code. Furthermore, ixgbe does send reset failure when it detects an empty mac address (35055928c). So I think it's safe to make igb behave the same. With this patch I can successfully run a Windows 8.1 guest with an empty mac address and an assigned igbvf device that has no mac address set by the host. If anyone is aware of a guest driver that chokes on NACK returns of VF RESET commands, please speak up.

2015-01-22igb: serialize access to the time sync interrupt registersRichard Cochran
The time sync related interrupt registers may be manipulated from different contexts. This patch protects the registers from being asynchronously changed by the reset function. Also, the patch removes a misleading comment. The reset function is disabling a bunch of functions, not enabling them.

2015-01-22igb: refactor time sync interrupt handlingRichard Cochran
The code that handles the time sync interrupt is repeated in three different places. This patch refactors the identical code blocks into a single helper function.

2015-01-22fm10k: Clean-up page reuse codeAlexander Duyck
This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.

2015-01-22e1000e: Fix 82572EI that has no hardware timestamp supportMathias Koehrer
With the Intel 82527EI (driver: e1000e) there is an issue when running the ptpd2 program, that leads to a kernel oops. The reason is here that in e1000_xmit_frame() a work queue will be scheduled that has not been initialized in this case. The work queue "tx_hwstamp_work" will only be initialized if adapter->flags & FLAG_HAS_HW_TIMESTAMP set. This check is missing in e1000_xmit_frame(). The following patch adds the missing check.

git://git.kernel.org/pub/scm/linux/kernel/git/jberg/mac80211-next Some further updates for net-next: * fix network-manager which was broken by the previous changes * fix delete-station events, which were broken by me making the genlmsg_end() mistake * fix a timer left running during suspend in some race conditions that would cause an annoying (but harmless) warning * (less important, but in the tree already) remove 80+80 MHz rate reporting since the spec doesn't distinguish it from 160 MHz; as the bitrate they're both 160 MHz bandwidth Signed-off-by: David S.

2015-01-19phonet netlink: allow multiple messages per skb in route dumpJohannes Berg
My previous patch to this file changed the code to be bug-compatible towards userspace. Unless userspace (which I wasn't able to find) implements the dump reader by hand in a wrong way, this isn't needed. If it uses libnl or similar code putting multiple messages into a single SKB is far more efficient. Change the code to do this. While at it, also clean it up and don't use so many variables - just store the address in the callback args directly. Signed-off-by: Johannes Berg <johannes.berg@intel.com> Signed-off-by: David S.
