2013-04-18igb: Fix sparse warnings on function pointersAkeem G. Abodunrin1-2/+2
This patch fixes sparse warnings on function pointers that are not defined as static.

2013-04-18igb: Use rx/tx_itr_setting when setting up initial value of itrAlexander Duyck1-0/+11
It turns out that the InterruptThrottleRate module parameter was only having the effect of locking the ITR at the starting ITR value. This was because the values stored in rx_itr_setting and tx_itr_setting were being ignored when configuring the initial itr_val of the q_vector.

2013-04-18igb: Pull adapter out of main path in igb_xmit_frame_ringAlexander Duyck1-9/+11
We only need the adapter pointer in the case of ptp. As such we can pull the adapter out of the main path and place it inside the if statement to avoid the temptation of accessing the adapter pointer in the fast path.

2013-04-18igb: Mask off check of frag_off as we only want fragment offsetAlexander Duyck1-1/+1
We were incorrectly checking the entire frag_off field when we only wanted the fragment offset. As a result we were not pulling in TCP headers when the DNF flag was set. To correct that we will now check for frag off using the IP_OFFSET mask.

2013-04-18Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-nextDavid S. Miller7-45/+162
Jeff Kirsher says: ==================== This series contains updates to ixgbe only. v2- Dropped the following 2 patches from the series: ixgbe: Support using build_skb in the case that jumbo frames are disabled ixgbe: walk pci-e bus to find minimum width Ben Hutchings found a bug with Alex's patch, so that patch was dropped permanently. Jacob's "walk PCIe bus" patch is being re-worked for a more generic solution so that other drivers can benefit. In the remaining patches... Alex provides a fix where we were incorrectly checking the entire frag_off field when we only wanted the fragment offset. Alex also cleans up the check for PAGE_SIZE, since the default configuration allocates 32K for all buffers. Emil provides a change to the calculation of eerd so that it is consistent between the read and write functions by using | instead of +. Jacob adds support for displaying PCIe Gen3 link speed, which was previously missing from the ixgbe driver. He also provides a patch to clean up ixgbe_get_bus_info_generic to call some conversion functions, which are used also in another patch provided by Jacob. Jacob modifies the driver to enable certain devices (which have an internal switch) to read from the physical slot rather than reading data from the internal switch. Don provides a couple of fixes (which are more appropriate for net-next), one of which resolves an issue where ixgbe was only turning on the laser when the adapter was up which caused issues for those who wanted to access the MNG firmware while the port was in a down state. The other fix is for WoL when currently linked at 1G. Lastly Don bumps the driver version keep the in-kernel driver up to date with the current functionality. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

2013-04-17ixgbe: Fix 1G link WoLDon Skidmore3-2/+8
We reset during the shutdown path which will reset AUTOC register. This would change LMS to 10G. If we were currently linked at 1G we will lose link, which is a bad thing if we wanted WoL to work. For the fix I needed to know if WoL is supported so I created a new bool in the ixgbe_hw struct. If this is set we will not allow the reset to change the current LMS value in AUTOC.

2013-04-17ixgbe: enable devices with internal switch to read pci parentJacob Keller1-0/+48
This patch modifies the driver to enable certain devices, which have an internal switch, to read data from the physical slot rather than reading data from the internal switch. The internal switch will always report the same PCI width and speed, which is not useful compared to knowing the width and speed of the slot the physical card is plugged into.

2013-04-11net/mlx4_core: Translate guest B0 steering rules to DMFSHadar Hen Zion1-22/+63
The different steering modes are global to the device, with DMFS being introduced after SRIOV was merged. Hence, SRIOV guests running legacy / older Linux kernels or non-Linux drivers may provide B0 steering directives when the hypervisor is using DMFS and fail. Under B0 only L2 steering rules are allowed, hence B0 is a subset of DMFS. Use this fact to enable such legacy guests to run by modifying the SRIOV B0 steering wrapper to translate guest B0 directives to DMFS ones when the device uses DMFS. The translated B0 rule has to be kept in the resource tracker as a B0 object to allow for lookup in case of detach.

Using bool can make code more readable. Convert uses and tests of int to bool. This also makes a comparison of tg3->link_up (itself bool) a bool comparison instead of int.
