Jeff Kirsher says: ==================== This series contains updates to e1000e, igb and ixgbe. Bruce Allan provide 2 minor cleanups for e1000e to resolve whitespace issues and build warnings about unused parameters. Carolyn provides a couple of fixes for igb, one being a fix for a possible panic when the interface is down and receive traffic arrives. The second fix resolves an issue on newer parts which have multiple checksum fields and set_ethtool was only checking to update the first checksum of the NVM image. Akeem provides majority of the changes in this patch set. Akeem provides a fix for e1000e on an issue reported from the community to resolve the issue of unlocking swflag_mutex for 82574 and 82583 devices even if the hardware semaphore was successfully acquired. The other patches from Akeem are against igb, where he adds support SFP module discovery, LED blink mechanism for devices using cathodes, LED support for i210/i211 parts and cleanup of a i2c function which was not being used. Matthew provides an update for igb to support a more accurate check for a PTP RX hang. Amir provides a patch for ixgbe to set the software prio_tc values at initialization to the hardware setting to remove the need to reset the device at the first time we call ixgbe_dcbnl_ieee_setets. ==================== Signed-off-by: NDavid S.

Set the SW prio_tc values at initialization to the HW setting. Setting the SW prio_tc default values to be the HW setting by reading the rtrup2tc register. For any TC change we need to reset the device. This will remove the need to reset the device at the first time we call ixgbe_dcbnl_ieee_setets.

In order to support a more accurate check for a PTP Rx hang where the device can no longer timestamp received packets, we need to update, per ring, when the last Rx timestamp was. Because of how the PTP Rx hang logic works, the current logic is valid, but properly updating the ring variable increases the accuracy of the check.

This patch fixes the issue of unlocking swflag_mutex for 82574 and 82583 devices regardless of if the hw semaphore has been successfully acquired via e1000_get_hw_semaphore_82574(). With this patch, unlocking mutex now depends on if the hw semaphore was successfully acquired before. And 82574/82583 devices are reset regardless of whether e1000_get_hw_semaphore_82574() returns success or failure.

There is currently no way for an Ethernet MAC driver servicing PHY link interrupts to notify this to the PHY state machine without defining its own state machine. Since most drivers are not so special, introduce a helper: phy_mac_interrupt() which can be called from a link up/down interrupt routine to update the PHY state machine. To avoid code duplication some refactoring has been done to expose the workqueue and its corresponding callback internally.

When a PHY device is registered with the special IRQ value PHY_IGNORE_INTERRUPT (-2) it will not properly be handled by the PHY library: - it continues to poll its register, while we do not want this because such PHY link events or register changes are serviced by an Ethernet MAC - it will still try to configure PHY interrupts at the PHY level, such interrupts do not exist at the PHY but at the MAC level - the state machine only handles PHY_POLL, but should also handle PHY_IGNORE_INTERRUPT similarly This patch updates the PHY state machine and initialization paths to account for the specific PHY_IGNORE_INTERRUPT. Based on an earlier patch by Thomas Petazzoni, and reworked to add the missing bits. Add a helper phy_interrupt_is_valid() which specifically tests for a PHY interrupt not to be PHY_POLL or PHY_IGNORE_INTERRUPT and use it throughout the code.

TCP md5 code uses per cpu variables but protects access to them with a shared spinlock, which is a contention point. [ tcp_md5sig_pool_lock is locked twice per incoming packet ] Makes things much simpler, by allocating crypto structures once, first time a socket needs md5 keys, and not deallocating them as they are really small. Next step would be to allow crypto allocations being done in a NUMA aware way. Signed-off-by: NEric Dumazet <edumazet@google.com> Cc: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: NDavid S.

A cpu executing the network receive path sheds packets when its input queue grows to netdev_max_backlog. A single high rate flow (such as a spoofed source DoS) can exceed a single cpu processing rate and will degrade throughput of other flows hashed onto the same cpu. This patch adds a more fine grained hashtable. If the netdev backlog is above a threshold, IRQ cpus track the ratio of total traffic of each flow (using 4096 buckets, configurable). The ratio is measured by counting the number of packets per flow over the last 256 packets from the source cpu. Any flow that occupies a large fraction of this (set at 50%) will see packet drop while above the threshold. Tested: Setup is a muli-threaded UDP echo server with network rx IRQ on cpu0, kernel receive (RPS) on cpu0 and application threads on cpus 2--7 each handling 20k req/s. Throughput halves when hit with a 400 kpps antagonist storm. With this patch applied, antagonist overload is dropped and the server processes its complete load. The patch is effective when kernel receive processing is the bottleneck. The above RPS scenario is a extreme, but the same is reached with RFS and sufficient kernel processing (iptables, packet socket tap, ..).
