2013-04-25ixgbe: add mac type to the version in ethtool_regsEmil Tantilov1-1/+2
This patch adds the mac type to the version in ethtool_regs. This will make it easier to check the mac type when dumping registers with ethtool. The drawback of this is that older versions of ethtool will only be able to dump in hex format for 82599 and above when used with the updated driver.

2013-04-25ixgbe: add support for disabling link at boot time on 82599Emil Tantilov2-2/+20

2013-04-25ixgbe: cache AUTOC readsEmil Tantilov2-16/+25
This patch removes majority of the AUTOC register reads by using a cached value instead. The reason for this change is to avoid writing corrupted values to AUTOC due to bad FW.

2013-04-25ixgbe: fix register access during ethtool loopback testEmil Tantilov1-12/+14
This patch cleans up the logic in ixgbe_setup_loopback_test() to only access registers applicable to the MAC type. AUTOC is only valid on MACs older than X540. MACC is used for X540. In addition it removes a read of AUTOC and uses the stored value to force the link up.

2013-04-25ixgbe: fix EICR write in ixgbe_msix_otherJacob Keller1-0/+10
Previously, the ixgbe_msix_other was writing the full 32bits of the set interrupts, instead of only the ones which the ixgbe_msix_other is handling. This resulted in a loss of performance when the X540's PPS feature is enabled due to sometimes clearing queue interrupts which resulted in the driver not getting the interrupt for cleaning the q_vector rings often enough. The fix is to simply mask the lower 16bits off so that this handler does not write them in the EICR, which causes them to remain high and be properly handled by the clean_rings interrupt routine as normal.

2013-04-25e1000e: fix numeric overflow in phc settime methodRichard Cochran1-2/+1
The PTP Hardware Clock settime function in the e1000e driver computes nanoseconds from a struct timespec. The code converts the seconds field .tv_sec by multiplying it with NSEC_PER_SEC. However, both operands are of type long, resulting in an unintended overflow. The patch fixes the issue by using the helper function from time.h.

When using the new bridge FDB interface to allow SR-IOV virtual function network devices to communicate with SW bridged network devices the physical function is placed into promiscuous mode and hardware VLAN filtering is disabled.

The be2net driver had a bug fix in 'net' that overlapped with the VLAN interface changes by Patrick McHardy in net-next. An IGB conflict existed because in 'net' the build_skb() support was reverted, and in 'net-next' there was a comment style fix within that code. Several batman-adv conflicts were resolved by making sure that all calls to batadv_is_my_mac() are changed to have a new bat_priv first argument. Eric Dumazet's TS ECR fix in TCP in 'net' conflicted with the F-RTO rewrite in 'net-next', mostly overlapping changes.

2013-04-18ixgbe: Fix a bug in setting VF VLAN via PFGreg Rose1-0/+6
The PF driver does not check if the administrator has already set a VF VLAN via the PF driver before setting the new VLAN. This results in the following scenario: A) Administrator sets VF <n> to VLAN 100 B) Administrator sets VF <x> to VLAN 100 C) Administrator sets VF <n> to VLAN 200 D) The VF <n> driver continues to be able to receive traffic on VLAN 100 because the VLVFB pool enable bit for that VF was left set instead of being cleared as it should be. This fix ensures that the old VLAN filter for VF <n> is first removed and the pool bit enable for VF <n> is cleared so that it no longer receives traffic on VLAN 100.

This patch actually reverts: igb: Support using build_skb in the case that jumbo frames are disabled The reason for reverting this patch is that it can lead to data corruption.

Second packet is received into the other half of this page 4. Page cannot be reused, so is DMA-unmapped 5.

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.

2013-04-17ixgbe: create conversion functions from link_status to bus/speedJacob Keller2-32/+34
This patch cleans up ixgbe_get_bus_info_generic to call some conversion functions, which are used also in a follow on patch that needs to convert between the link_status PCIe config values into ixgbe's internal enum representations.

2013-04-17ixgbe: Enable support for recognizing PCI-e Gen3 link speedJacob Keller3-1/+7
This patch adds support for displaying PCIe Gen3 link speed, which was previously missing from the driver. Signed-off-by: Jacob Keller <[email protected]> Tested-by: Phil Schmitt <[email protected]> Signed-off-by: Jeff Kirsher <[email protected]>
2013-04-17ixgbe: Drop check for PAGE_SIZE from ixgbe_xmit_frame_ringAlexander Duyck1-6/+1
The check for PAGE_SIZE is pointless now that the default configuration is to allocate 32K for all buffers. Since the Tx descriptor limit is 16K we can just drop the check and always compare the descriptors to the maximum size supported.
