| * | | | | | | | | | bnx2x: Prevent probe as early as possibleYuval Mintz2015-03-31

This adds a check as early as possible so that driver will not read junk values and make incorrect probe decisions according to them; instead, gracefully fail the probe.

In this time the transceiver doesn't leave the TX_ON/TX_ARET_ON state until the tx complete irq change the state into RX_AACK_ON again. This means a receiving interrupt in state TX_ON/TX_ARET_ON can't happen and is_tx is protected by transceiver.

In theses cases actually the new type is __kernel_time_t which is __kernel_long_t which unfortunately can be either "long" or "long long". So to solve this I cases the arguments to "long long". -DaveM Richard Cochran says: ==================== ptp: get ready for 2038 This series converts the core driver methods of the PTP Hardware Clock (PHC) subsystem to use the 64 bit version of the timespec structure, making the core API ready for the year 2038. In addition, I reviewed how each driver and device represents the time value at the hardware register level. Most of the drivers are ready, but a few will need some work before the year 2038, as shown: Patch Driver ------------------------------------------------ 12 drivers/net/ethernet/intel/igb/igb_ptp.c 15 ? drivers/net/ethernet/sfc/ptp.c 16 drivers/net/ethernet/stmicro/stmmac/stmmac_ptp.c The commit log messages document how each driver is ready or why it is not ready. For patch 15, I could not easily find out the hardware representation of the time value, and so the SFC maintainers will have to review their low level code in order to resolve any remaining issues. * ChangeLog ** V3 - dp83640: use timespec64 throughout per Arnd's suggestion - tilegx: use timespec64 throughout per Chris' suggestion - add Jeff's acked-bys ** V2 - use the new methods in the posix clock code right away (patch #3) ==================== Signed-off-by: David S.

Jesse adds new device IDs to handle the new 20G speed for KR2. Mitch provides a fix for an issue that shows up as a panic or memory corruption when the device is brought down while under heavy stress. This is resolved by delaying the releasing of resources until we receive acknowledgment from the PF driver that the rings have indeed been stopped. Also adds firmware version information to ethtool reporting to align with ixgbevf behavior. Akeem increases the polling loop limiter, sine we found that in certain circumstances the firmware can take longer to be ready after a reset. ==================== Signed-off-by: David S.

This stops the stack from hitting us with transmits while we're shutting down. Additionally, disable NAPI before disabling interrupts, or the interrupt might get re-enabled inappropriately. Finally, remove the call to netif_tx_stop_all_queues, as it is redundant - the call to netif_tx_disable already did the same thing.

This shows up as a panic or memory corruption when the device is brought down while under heavy stress. To fix this, delay releasing resources until we receive acknowledgment from the PF driver that the rings have indeed been stopped. Because of this delay, we also need to check to make sure that all of our admin queue requests have been handled before allowing the device to be opened.

Having it set causes DSA tagged packets to be sent to the CPU port roughly every 30 seconds. Those packets are the same as real packets forwarded between switch ports if the switch is configured for switching between multiple ports. The packets are then bridged by the software bridge, resulting in duplicated packets on the network.
