2020-12-09igb: avoid transmit queue timeout in xdp pathSven Auhagen1-0/+5
Since we share the transmit queue with the network stack, it is possible that we run into a transmit queue timeout. This will reset the queue. This happens under high load when XDP is using the transmit queue pretty much exclusively. netdev_start_xmit() sets the trans_start variable of the transmit queue to jiffies which is later utilized by dev_watchdog(), so to avoid timeout, let stack know that XDP xmit happened by bumping the trans_start within XDP Tx routines to jiffies.

2020-09-29net: intel: Remove in_interrupt() warningsSebastian Andrzej Siewior1-1/+0
in_interrupt() is ill defined and does not provide what the name suggests. The usage especially in driver code is deprecated and a tree wide effort to clean up and consolidate the (ab)usage of in_interrupt() and related checks is happening. In this case the checks cover only parts of the contexts in which these functions cannot be called. They fail to detect preemption or interrupt disabled invocations. As the functions which are invoked from the various places contain already a broad variety of checks (always enabled or debug option dependent) cover all invalid conditions already, there is no point in having inconsistent warnings in those drivers. Just remove them.

2020-09-28igb: add XDP supportSven Auhagen3-36/+481
Add XDP support to the IGB driver. The implementation follows the IXGBE XDP implementation closely and I used the following patches as basis: 1. commit 924708081629 ("ixgbe: add XDP support for pass and drop actions") 2. commit 33fdc82f0883 ("ixgbe: add support for XDP_TX action") 3. commit ed93a3987128 ("ixgbe: tweak page counting for XDP_REDIRECT") Due to the hardware constraints of the devices using the IGB driver we must share the TX queues with XDP which means locking the TX queue for XDP. I ran tests on an older device to get better numbers. Test machine: Intel(R) Atom(TM) CPU C2338 @ 1.74GHz (2 Cores) 2x Intel I211 Routing Original Driver Network Stack: 382 Kpps Routing XDP Redirect (xdp_fwd_kern): 1.48 Mpps XDP Drop: 1.48 Mpps Using XDP we can achieve line rate forwarding even on an older Intel Atom CPU.

2020-06-25net/intel: remove driver versions from Intel driversJeff Kirsher3-12/+1
As with other networking drivers, remove the unnecessary driver version from the Intel drivers. The ethtool driver information and module version will then report the kernel version instead. For ixgbe, i40e and ice drivers, the driver passes the driver version to the firmware to confirm that we are up and running. So we now pass the value of UTS_RELEASE to the firmware. This adminq call is required per the HAS document. The Device then sends an indication to the BMC that the PF driver is present. This is done using Host NC Driver Status Indication in NC-SI Get Link command or via the Host Network Controller Driver Status Change AEN. What the BMC may do with this information is implementation-dependent, but this is a standard NC-SI 1.1 command we honor per the HAS.

2020-05-22igb: Report speed and duplex as unknown when device is runtime suspendedKai-Heng Feng1-1/+2
igb device gets runtime suspended when there's no link partner. We can't get correct speed under that state: $ cat /sys/class/net/enp3s0/speed 1000 In addition to that, an error can also be spotted in dmesg: [ 385.991957] igb 0000:03:00.0 enp3s0: PCIe link lost Since device can only be runtime suspended when there's no link partner, we can skip reading register and let the following logic set speed and duplex with correct status. The more generic approach will be wrap get_link_ksettings() with begin() and complete() callbacks. However, for this particular issue, begin() calls igb_runtime_resume() , which tries to rtnl_lock() while the lock is already hold by upper ethtool layer. So let's take this approach until the igb_runtime_resume() no longer needs to hold rtnl_lock.

2020-02-24intel: Replace zero-length array with flexible-array memberGustavo A. R. Silva1-1/+1
The current codebase makes use of the zero-length array language extension to the C90 standard, but the preferred mechanism to declare variable-length types such as these ones is a flexible array member[1][2], introduced in C99: struct foo { int stuff; struct boo array[]; }; By making use of the mechanism above, we will get a compiler warning in case the flexible array does not occur last in the structure, which will help us prevent some kind of undefined behavior bugs from being inadvertently introduced[3] to the codebase from now on. Also, notice that, dynamic memory allocations won't be affected by this change: "Flexible array members have incomplete type, and so the sizeof operator may not be applied. As a quirk of the original implementation of zero-length arrays, sizeof evaluates to zero."[1] This issue was found with the help of Coccinelle.

User space may request time stamps on rising edges, falling edges, or both. However, the particular mode may or may not be supported in the hardware or in the driver. This patch adds a "strict" flag that tells drivers to ensure that the requested mode will be honored. Signed-off-by: Richard Cochran <richardcochran@gmail.com> Signed-off-by: David S.

2019-11-15igb: reject unsupported external timestamp flagsJacob Keller1-0/+6
Fix the igb PTP support to explicitly reject any future flags that get added to the external timestamp request ioctl. In order to maintain currently functioning code, this patch accepts all three current flags. This is because the PTP_RISING_EDGE and PTP_FALLING_EDGE flags have unclear semantics and each driver seems to have interpreted them slightly differently. This HW always time stamps both edges: flags Meaning ---------------------------------------------------- -------------------------- PTP_ENABLE_FEATURE Time stamp both edges PTP_ENABLE_FEATURE|PTP_RISING_EDGE Time stamp both edges PTP_ENABLE_FEATURE|PTP_FALLING_EDGE Time stamp both edges PTP_ENABLE_FEATURE|PTP_RISING_EDGE|PTP_FALLING_EDGE Time stamp both edges Signed-off-by: Jacob Keller <jacob.e.keller@intel.com> Tested-by: Aaron Brown <aaron.f.brown@intel.com> Signed-off-by: David S.

2019-11-15net: reject PTP periodic output requests with unsupported flagsJacob Keller1-0/+4
Commit 823eb2a3c4c7 ("PTP: add support for one-shot output") introduced a new flag for the PTP periodic output request ioctl. This flag is not currently supported by any driver. Fix all drivers which implement the periodic output request ioctl to explicitly reject any request with flags they do not understand. This ensures that the driver does not accidentally misinterpret the PTP_PEROUT_ONE_SHOT flag, or any new flag introduced in the future. This is important for forward compatibility: if a new flag is introduced, the driver should reject requests to enable the flag until the driver has actually been modified to support the flag in question.

2019-11-08igb/igc: use ktime accessors for skb->tstampJacob Keller1-2/+2
When implementing launch time support in the igb and igc drivers, the skb->tstamp value is assumed to be a s64, but it's declared as a ktime_t value. Although ktime_t is typedef'd to s64 it wasn't always, and the kernel provides accessors for ktime_t values. Use the ktime_to_timespec64 and ktime_set accessors instead of directly assuming that the variable is always an s64. This improves portability if the code is ever moved to another kernel version, or if the definition of ktime_t ever changes again in the future.

Changing a network device MTU can be a fairly frequent operation, and failure to change the MTU is reflected to user-space properly, both by an appropriate message as well as by looking at whether the device's MTU matches the configuration. Demote the prints to debug prints by using netdev_dbg(), making all Intel wired LAN drivers consistent, since they used a mixture of PCI device and network device prints before.

2019-11-01igb: Fix constant media auto sense switching when no cable is connectedManfred Rudigier1-1/+2
At least on the i350 there is an annoying behavior that is maybe also present on 82580 devices, but was probably not noticed yet as MAS is not widely used. If no cable is connected on both fiber/copper ports the media auto sense code will constantly swap between them as part of the watchdog task and produce many unnecessary kernel log messages. The swap code responsible for this behavior (switching to fiber) should not be executed if the current media type is copper and there is no signal detected on the fiber port. In this case we can safely wait until the AUTOSENSE_EN bit is cleared.

This patch enables the hardware feature "Media Auto Sense" also on the i350. It works in the same way as on the 82850 devices. Hardware designs using dual PHYs (fiber/copper) can enable this feature by setting the MAS enable bits in the NVM_COMPAT register (0x03) in the EEPROM.

2019-10-31igb/igc: Don't warn on fatal read failures when the device is removedLyude Paul1-1/+2
Fatal read errors are worth warning about, unless of course the device was just unplugged from the machine - something that's a rather normal occurrence when the igb/igc adapter is located on a Thunderbolt dock. So, let's only WARN() if there's a fatal read error while the device is still present. This fixes the following WARN splat that's been appearing whenever I unplug my Caldigit TS3 Thunderbolt dock from my laptop: igb 0000:09:00.0 enp9s0: PCIe link lost ------------[ cut here ]------------ igb: Failed to read reg 0x18!
