Soon, listener socket wont be locked when tcp_openreq_init_rwin() is called. We need to read socket fields once, as their value could change under us. Signed-off-by:

Stephen Hemminger says: ==================== l2tp: module autoloading With L2TP it was necessary to manually load modules which is a nuisance and not required with other tunneling protocols. This set of patches adds the aliases and module load hook to get rid of the necessity of modprobing. ==================== Acked-By:

When creating a IP encapsulated tunnel the necessary l2tp module should be loaded. It already works for UDP encapsulation, it just doesn't work for direct IP encap. Signed-off-by:

It should not be necessary to do explicit module loading when configuring L2TP. Modules should be loaded as needed instead (as is done already with netlink and other tunnel types). This patch adds a new module alias type and code to load the sub module on demand. Signed-off-by:

There will be needed to have switchdev_trans available down in the call chain, so propagate it instead of trans phase enum. This enum will be removed anyway. Also, use prepare/commit phase check helpers to get information about current phase of transaction. Signed-off-by:

Now, the memory allocation in prepare/commit state is done separatelly in each driver (rocker). Introduce the similar mechanism in generic switchdev code, in form of queue. That can be used not only for memory allocations, but also for different items. Abort item destruction is handled as well. Signed-off-by:

Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-09-23 This series contains updates to ixgbe only. Mark provides all the changes in this series, first clears the destination location for I2C data initially so that the received data will not be corrupted by previous attempts. Then reduced the pauses/delays in the PHY detection when no SFP is present by reducing the number of retires, once an SFP is detected, the "normal" number of retries in PHY detection will be used. Added support for X55EM_x SFP+ dual-speed, and fixed 1G and 10G link stability for X550EM_x by configuring the CS4227 correctly by moving code to ixgbe_setup_mac_link_sfp_x550em(). Added functionality to reset CS4227, since on some platforms the CS4227 does not initialize properly. Next reduces the SFP polling rate, due to when an SFP is not present, the I2C timeouts that result are very costly. So prevent the SFP polling from being done more than once every two seconds. Added support for I2C bus MUX. Fixed the setting of RDRXCTL register which should fall through X540 and 82599, not 82598. In addition, added small packet padding support in X550 by setting RDRXCTL.PSP when the driver is in SRIOV mode. Fixed a known hardware issue where the PCI transactions pending bit sticks high when there are pending transactions, so workaround the issue by wait and then continue with our reset flow. Added a new device ID for X550EM device with SFPs. Provided a fix with the DCA setup, which was suggested by Alex Duyck <aduyck@mirantis.com>, by making it so that we always set the relaxed ordering bits related to the DCA registers even if DCA is not enbaled. Then moves the configuration out of the ixgbe_down() and into ixgbe_configure() before enabling the transmit and receive rings. This ensures that DCA is configured correctly before starting the processing of packets. Fixed VM-to-VM loopback mode which requires that FCRTH be set, but the datasheets did not specify what the value should be. It has now been determined that the correct value should be RXPBSIZE - (24*1024). ==================== Signed-off-by: -

The 82599 and X540 datasheets require that FCRTH be "set" for Tx switching (VM-to-VM loopback) but it did not previously specify what the value should be set to. It has now been determined that the correct value is RXPBSIZE - (24*1024). This setting is also required for later devices. Signed-off-by:

This change does two things. First, it makes it so that we always set the relaxed ordering bits related to the DCA registers even if DCA is not enabled. Second, it moves the configuration out of the ixgbe_down function and into the ixgbe_configure function before enabling the Rx and Tx rings. This ensures that DCA is configured correctly before starting to process packets. Thanks to Alex Duyck for this fix. CC: Alex Duyck <aduyck@mirantis.com> Signed-off-by:

Mark Rustad authored
Take control of an I2C mux that selects which SFP is attached to the I2C bus. The control of the mux is captured in the taking and releasing of the related semaphore. Because only port 1 can control the mux, port 1 always leaves the mux set to select port 0. Signed-off-by:

Reduce the frequency of polling for SFP modules. Because the service task sometimes runs at high rates, we can poll for SFPs too often. When an SFP is not present, the I2C timeouts that result are very costly. So, prevent SFP polling from being done more than once every two seconds. To reduce latency, the poll time is cleared in a couple of cases to permit the next service task execution to poll the SFP module. Signed-off-by:

Mark Rustad authored
Configures the CS4227 correctly for both 1G and 10G operation, by moving the code to ixgbe_setup_mac_link_sfp_x550em(). It needs to be in this function because we need both the module type and the speed, and this is the only function in the init flow that knows the speed. In contrast, ixgbe_setup_sfp_modules_X550em() does not know the speed, so we can't do anything useful here. This is a fundamental difference from the previous flow, and is due to the way the CS4227 is implemented. Signed-off-by:
