2014-03-08ixgbevf: fix skb->pkt_type checksFlorian Fainelli1-1/+2
skb->pkt_type is not a bitmask, but contains only value at a time from the range defined in include/uapi/linux/if_packet.h. Checking it like if it was a bitmask of values would also cause PACKET_OTHERHOST, PACKET_LOOPBACK and PACKET_FASTROUTE to be matched by this check since their lower 2 bits are also set, although that does not fix a real bug, it is still potentially confusing. This bogus check was introduced in commit 815cccbf ("ixgbe: add setlink, getlink support to ixgbe and ixgbevf").

2014-03-07e1000e: Fix SHRA register access for 82579David Ertman2-2/+2
Previous commit c3a0dce35af0 fixed an overrun for the RAR on i218 devices. This commit also attempted to homogenize the RAR/SHRA access for all parts accessed by the e1000e driver. This change introduced an error for assigning MAC addresses to guest OS's for 82579 devices. Only RAR[0] is accessible to the driver for 82579 parts, and additional addresses must be placed into the SHRA[L|H] registers. The rar_entry_count was changed in the previous commit to an inaccurate value that accounted for all RAR and SHRA registers, not just the ones usable by the driver. This patch fixes the count to the correct value and adjusts the e1000_rar_set_pch2lan() function to user the correct index.

2014-03-07e1000e: Fix not generating an error on invalid load parameterDavid Ertman1-0/+6
Valid values for InterruptThrottleRate are 10-100000, or one of 0, 1, 3, 4. '2' is not valid. This is a legacy from the branching from the e1000 driver code that e1000e was based from. Prior to this patch, if the e1000e driver was loaded with a forced invalid InterruptThrottleRate of '2', then no throttle rate would be set and no error message generated. Now, a message will be generated that an invalid value was used and the value for InterruptThrottleRate will be set to the default value.

2014-03-07e1000e: Feature Enable PHY Ultra Low Power Mode (ULP)David Ertman6-33/+354
ULP is a power saving feature that reduces the power consumption of the PHY when a cable is not connected. ULP is gated on the following conditions: 1) The hardware must support ULP. Currently this is only I218 devices from Intel 2) ULP is initiated by the driver, so, no driver results in no ULP. 3) ULP's implementation utilizes Runtime Power Management to toggle its execution. ULP is enabled/disabled based on the state of Runtime PM. 4) ULP is not active when wake-on-unicast, multicast or broadcast is active as these features are mutually-exclusive. Since the PHY is in an unavailable state while ULP is active, any access of the PHY registers will fail. This is resolved by utilizing kernel calls that cause the device to exit Runtime PM (e.g. pm_runtime_get_sync) and then, after PHY access is complete, allow the device to resume Runtime PM (e.g. pm_runtime_put_sync). Under certain conditions, toggling the LANPHYPC is necessary to disable ULP mode. Break out existing code to toggle LANPHYPC to a new function to avoid code duplication.

2014-03-07e1000e: Refactor PM flowsDavid Ertman3-55/+78
Refactor the system power management flows to prevent the suspend path from being executed twice when hibernating since both the freeze and poweroff callbacks were set to e1000_suspend() via SET_SYSTEM_SLEEP_PM_OPS. There are HW workarounds that are performed during this flow and calling them twice was causing erroneous behavior. Re-arrange the code to take advantage of common code paths and explicitly set the individual dev_pm_ops callbacks for suspend, resume, freeze, thaw, poweroff and restore. Add a boolean parameter (reset) to the e1000e_down function to allow for cases when the HW should not be reset when downed during a PM event. Now that all suspend/shutdown paths result in a call to __e1000_shutdown() that checks Wake on Lan status, removing redundant check for WoL in e1000_power_down_phy().

2014-03-07e1000e: Resolve issues with Management Engine (ME) briefly blocking PHY resetsDavid Ertman1-4/+26
On a ME enabled system with the cable out, the driver init flow would generate an erroneous message indicating that resets were being blocked by an active ME session. Cause was ME clearing the semaphore bit to block further PHY resets for up to 50 msec during power-on/cycle. After this interval, ME would re-set the bit and allow PHY resets. To resolve this, change the flow of e1000e_phy_hw_reset_generic() to utilize a delay and retry method. Poll the FWSM register to minimize any extra time added to the flow. If the delay times out at 100ms (checked in 10msec increments), then return the value E1000_BLK_PHY_RESET, as this is the accurate state of the PHY. Attempting to alter just the call to e1000e_phy_hw_reset_generic() in e1000_init_phy_workarounds_pchlan() just caused the problem to move further down the flow.

2014-03-04be2net: dma_sync each RX frag before passing it to the stackSathya Perla2-11/+24
The driver currently maps a page for DMA, divides the page into multiple frags and posts them to the HW. It un-maps the page after data is received on all the frags of the page. This scheme doesn't work when bounce buffers are used for DMA (swiotlb=force kernel param). This patch fixes this problem by calling dma_sync_single_for_cpu() for each frag (excepting the last one) so that the data is copied from the bounce buffers. The page is un-mapped only when DMA finishes on the last frag of the page. (Thanks Ben H. for suggesting the dma_sync API!) This patch also renames the "last_page_user" field of be_rx_page_info{} struct to "last_frag" to improve readability of the fixed code.

This patch fixes a CPDMA RX Descriptor leak that occurs after taking the interface down when the CPSW is in Dual MAC mode. Previously the CPSW_ALE port was left open up which causes packets to be received and processed by the RX interrupt handler and were passed to the non active network interface where they were ignored. The fix is for the slave_stop function of the selected interface to disable the respective CPSW_ALE Port from forwarding packets. This blocks traffic from being received on the inactive interface.

2014-03-02ixgbe: implement SIOCGHWTSTAMP ioctlJacob Keller3-8/+24
This patch adds support for the new SIOCGHWTSTAMP ioctl, which enables a process to determine the current timestamp configuration. In order to implement this, store a copy of the timestamp configuration. In addition, we can remove the 'int cmd' parameter as the new set_ts_config function doesn't use it. I also fixed a typo in the function description. -v2 * Only save the settings after validating them Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Phil Schmitt <phillip.j.schmitt@intel.com> Signed-off-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

2014-03-02b44: always set duplex mode why phy changesHauke Mehrtens1-1/+6
Without this patch b44_check_phy() was called when the phy called the adjust callback. This method only change the mac duplex mode when the carrier was off. When the phy changed the duplex mode after the carrier was on the mac was not changed. This happened when an external phy was used.
