The ibmvnic_change_mac_addr struct alignment was not matching the defined format in PAPR+, it had the reserved and return code fields swapped. As a consequence, the CHANGE_MAC_ADDR_RSP commands were being improperly handled and executed even when the operation wasn't successfully completed by the system firmware.

Constants used for tuning are generally a bad idea, especially as hardware changes over time. Replace the constant 2 jiffies with sysctl variable netdev_budget_usecs to enable sysadmins to tune the softirq processing. Also document the variable. For example, a very fast machine might tune this to 1000 microseconds, while my regression testing 486DX-25 needs it to be 4000 microseconds on a nearly idle network to prevent time_squeeze from being incremented. Version 2: changed jiffies to microseconds for predictable units. Signed-off-by: NMatthew Whitehead <tedheadster@gmail.com> Signed-off-by: NDavid S. Miller <davem@davemloft.net>

This feature allows the administrator to set an fwmark for packets traversing a tunnel. This allows the use of independent routing tables for tunneled packets without the use of iptables. There is no concept of per-packet routing decisions through IPv4 tunnels, so this implementation does not need to work with per-packet route lookups as the v6 implementation may (with IP6_TNL_F_USE_ORIG_FWMARK). Further, since the v4 tunnel ioctls share datastructures (which can not be trivially modified) with the kernel's internal tunnel configuration structures, the mark attribute must be stored in the tunnel structure itself and passed as a parameter when creating or changing tunnel attributes.

Jeff Kirsher says: ==================== 10GbE Intel Wired LAN Driver Updates 2017-04-18 This series contains updates to mainly ixgbe with only one ixgbevf change. Usha adds a check to ensure the creation of number of VF's is valid based on the traffic classes configured, all to avoid transmit hangs. Joe Perches reduces the use of pr_cont since the output can be interleaved by other processes. Tony cleans up the code overwriting the KX4 config, which is configured by the NVM. Adds a check for MMNGC.MNG_VETO, to resolve an issue where we were getting a link loss for the BMC when loading the driver. Don fixes up SGMII x553 config details which were missed in earlier implementations. Added support for x552 XFI backplane interface support. Cleaned up an unused define, which was causing confusion on supported devices. Emil fixes a link issue on KR parts by making sure the default setting is set. Refactors the code so that the code for allocating memory for the list of MAC addresses that the VFs can use into its own function. Made some code cleans to help readability and ensure notification of SRIOV being enabled is done upon completion. Fixed an issue where if we failed to allocate vfinfo in __ixgbe_enable_sriov() the driver would crash with a NULL pointer dereference. Philippe Reynes updates ixgbevf to use the new API for {get|set}_link_ksettings. Alex increases the headroom allocation when using build_skb() on a system with 4K pages. Fixed an issue in ixgbe_dump() where we were no longer clearing the status bit. ==================== Signed-off-by: NDavid S. Miller <davem@davemloft.net>

When using TCP FastOpen for an active session, we send one wakeup event from tcp_finish_connect(), right before the data eventually contained in the received SYNACK is queued to sk->sk_receive_queue. This means that depending on machine load or luck, poll() users might receive POLLOUT events instead of POLLIN|POLLOUT To fix this, we need to move the call to sk->sk_state_change() after the (optional) call to tcp_rcv_fastopen_synack() Signed-off-by: NEric Dumazet <edumazet@google.com> Acked-by: NYuchung Cheng <ycheng@google.com> Signed-off-by: NDavid S.

由 Eric Dumazet 提交于
When a RST packet is processed, we send two wakeup events to interested polling users. First one by a sk->sk_error_report(sk) from tcp_reset(), followed by a sk->sk_state_change(sk) from tcp_done(). Depending on machine load and luck, poll() can either return POLLERR, or POLLIN|POLLOUT|POLLERR|POLLHUP (this happens on 99 % of the cases) This is probably fine, but we can avoid the confusion by reordering things so that we have more TCP fields updated before the first wakeup.

When there is no FID set for a specific packet, the HW will drop it. However, by default these packets are useful to be delivered to CPU as it can inspect them and program HW accordingly. So add this trap. This would only ever happen when port is enslaved to an OVS master. Otherwise, packets would be dropped during VLAN / STP filtering, before FID classification.

Juergen Borleis says: ==================== net: dsa: add SMSC/Microchip LAN9303 three port ethernet switch driver The LAN9303 is a three port 10/100 ethernet switch with integrated phys for the two external ethernet ports. The third port is an RMII/MII interface to a host master network interface (e.g. fixed link). While the LAN9303 device itself supports offload packet processing, this driver does not make use of it yet. This driver just configures the device to provide two separate network interfaces (which is the default state of a DSA device). Please note: the "MDIO managed mode" driver part isn't tested yet. I have used and tested the "I2C managed mode" only. Changes in v6: - fix support to use the driver as a module (core, i2c and mdio) - license info added in all parts of the driver (for module support) Changes in v5: - add missing include file to 'net/dsa/tag_lan9303.c' Changes in v4: - rebased on net-next, 'net/dsa/tag_lan9303.c' adapted to changed API Changes in v3: - 'ds_to_lan9303()' removed - special PHY reg MII_LAN911X_SPECIAL_CONTROL_STATUS mapping removed - compatible strings for I2C and MDIO are now different - MDIO-managed-mode devicetree binding added (still compile time tested only) Changes in v2: - code moved to 'drivers/net/dsa' - timeouts in completion wait loops - macros instead of various magic numbers - development code removed - devicetree property names changed - devicetree example adapted - tried to avoid to mix 'switching' and 'forwarding'...
