o Adapter provides communication channel between VF and PF. Any control commands from the VF driver are sent to the PF driver through this communication channel. PF driver validates the commands before sending them to the adapter. Similarly PF driver forwards any control command responses to the VF driver through this communication channel. Adapter sends message pending event to VF or PF when there is an outstanding response or a command for VF or PF respectively. When a command or a response is sent over a channel VF or PF cannot send another command or a response until adapter sends a channel free event. Adapter allocates 1K area to VF and PF each for this communication. o Commands and responses are encapsulated in a header. Header determines sequence id, number of fragments, fragment number etc. Signed-off-by:

o Add QLCNIC_SRIOV to Kconfig. o Provide PCI sysfs hooks to enable and disable SR-IOV. o Allow enabling only when CONFIG_QLCNIC_SRIOV is defined. o qlcnic_sriov_pf.c has all the PF related SR-IOV functionality. o qlcnic_sriov_common.c has VF functionality and SR-IOV functionality which is common between VF and PF. o qlcnic_sriov.h is a common header file for SR-IOV defines.

The CONFIG_ARCH_IXDP2X01 and CONFIG_MACH_IXDP2351 Kconfig macros are unused since the ixp23xx and ixp2000 platforms were removed in v3.5. So remove the last code still depending on these macros. And since CS89x0_NONISA_IRQ was only set if either of these two macros was defined we can also remove that macro and the code depending on it. Signed-off-by:

Commit d0418bb7 (net: sh_eth: Add eth support for R8A7779 device) was a failed attempt to add support for one of members of the R-Car SoC family. That's for three reasons: it treated R8A7779 the same as SH7724 except including quite dirty hack adding ECMR_ELB bit to the mask in sh_eth_set_rate() while not removing ECMR_RTM bit (despite it's reserved in R-Car Ether), and it didn't add a new register offset array despite the closest SH_ETH_REG_FAST_SH4 mapping differs by 0x200 to the offsets all the R-Car Ether registers have, and also some of the registers in this old mapping don't exist on R-Car Ether (due to this, SH7724's 'sh_eth_my_cpu_data' structure is not adequeate for R-Car too). Fix all these shortcomings, restoring the SH7724 related section to its pristine state... Signed-off-by:

The core has a bit for swapping packet data endianism. Reset default from Cadence is off. Xilinx however, who uses this core on the Zynq SoCs, opted for on. Force it to off. This shouldn't change the behaviour for current users of the macb, but enables usage on Zynq devices. Signed-off-by:

Jeff Kirsher says: ==================== This series contains updates to e1000e, ixgbe and ixgbevf. Majority of the changes are against e1000e (from Bruce Allan). Bruce adds additional error handling on PHY register access, as well as improve slow performance on 82579 when connected to a 10Mbit hub. In addition, fixes LED blink logic for cathode LED design. Most notable is added EEE support which is enabled by default and the added support for LTR on I217/I218. The ixgbe and ixgbevf from Greg Rose changes the VM so that if a user does not assign a MAC address, the MAC address is set to all zeros instead of a random MAC address. This ensures that we always know when we have a random address and udev won't get upset about it. ==================== Signed-off-by: -

Included changes: - A fix for the network coding component which has been added within the last pull request (so it is in linux-3.10). The problem has been spotted thanks to Fengguang Wu's automated daily checks on our tree. - Implementation of the RTNL API for virtual interface creation/deletion and slave manipulation - substitution of seq_printf with seq_puts when possible - minor cleanups Signed-off-by: -

The previous commit ce43a216 (e1000e: cleanup USLEEP_RANGE checkpatch checks) converted a number of delays and sleeps as recommended in ./Documentation/timers/timers-howto.txt. Unfortunately, a few of the udelay() to usleep_range() conversions are in code paths that are in an atomic context in which usleep_range() should not be used. Revert those specific changes.

Set the Latency Tolerance Reporting (LTR) values for the "PCIe-like" GbE MAC in the Lynx Point PCH based on Rx buffer size and link speed when link is up (which must not exceed the maximum latency supported by the platform), otherwise specify there is no LTR requirement. Unlike true-PCIe devices which set the LTR maximum snoop/no-snoop latencies in the LTR Extended Capability Structure in the PCIe Extended Capability register set, on this device LTR is set by writing the equivalent snoop/no-snoop latencies in the LTRV register in the MAC and set the SEND bit to send an Intel On-chip System Fabric sideband (IOSF-SB) message to the PMC.

Devices supported by the driver which support EEE (currently 82579, I217 and I218) are advertising EEE capabilities during auto-negotiation even when EEE has been disabled. In addition to not acting as expected, this also caused the EEE status reported by 'ethtool --show-eee' to be wrong when two of these devices are connected back-to-back and EEE is disabled on one. In addition to fixing this issue, the ability for the user to specify which speeds (100 or 1000 full-duplex) to advertise EEE support has been added. Signed-off-by:

When the MAC and PHY are in two different modes (different power levels and interconnect speeds), it could take a long time before a PHY register access timed out using the existing MAC-PHY interconnect configuration coded into the driver for ICH- and PCH-based LOMs. Introduce an I217/I218- specific .setup_physical_interface operation which does not override the interconnect configuration in the NVM.

Two 82579 LOMs connected via a 10Mb hub experience extraordinarily low performance. This is because 82579 is excessively aggressive on transmit at 10Mb half-duplex and will not provide sufficient time for the link partner to transmit. When the link partner is also 82579, the result is a lot of collisions (and corresponding re-transmits) that cause the poor performance. To work-around this issue, significantly increase the IPG in the MAC to allow enough gap for the link partner to transmit and reduce the Rx latency in the analog PHY to 0 to reduce the number of collisions.

PHY reads/writes via the MDIC register could potentially return results from a previous PHY register access. If that happens, the offset in the returned results will be that of the previous access and if that is different from the expected offset, log a debug message and error out. Signed-off-by:

Add a new constant ETH_P_802_3_MIN, the minimum ethernet type for an 802.3 frame. Frames with a lower value in the ethernet type field are Ethernet II. Also update all the users of this value that David Miller and I could find to use the new constant. Also correct a bug in util.c. The comparison with ETH_P_802_3_MIN should be >= not >.
