This function is used to build and send SYNACK packets, possibly on behalf of unlocked listener socket. Make sure we did not miss a write by making this socket const. We no longer can use ip_select_ident() and have to either set iph->id to 0 or directly call __ip_select_ident() Signed-off-by: NEric Dumazet <edumazet@google.com> Signed-off-by: NDavid S.

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: NDavid S. Miller <davem@davemloft.net>

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.
