2014-07-07vxlan: Call udp_flow_src_portTom Herbert
In vxlan and OVS vport-vxlan call common function to get source port for a UDP tunnel. Removed vxlan_src_port since the functionality is now in udp_flow_src_port. Signed-off-by: Tom Herbert <therbert@google.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07net: systemport: add Wake-on-LAN supportFlorian Fainelli
Support for Wake-on-LAN using Magic Packet with or without SecureOn password is implemented doing the following: - setting the password to the relevant UniMAC registers - flagging the device as a wakeup source for the system, as well as its Wake-on-LAN interrupt - prepare the hardware for entering WoL mode - enabling the MPD interrupt to wake us The Device Tree binding documentation is also reflected to specify the third optional Wake-on-LAN interrupt line.

2014-07-07net: systemport: rename rx_csum_en to rx_chk_enFlorian Fainelli
This boolean tells us whether we are using the RXCHK hardware block, so use a variable name that reflects that. RXCHK might be used in the future to implement Wake-on-LAN using ARP or unicast packets. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07net: systemport: add suspend and resume supportFlorian Fainelli
Implement the hardware recommended suspend/resume procedure for SYSTEMPORT. We leverage the previous factoring work such that we can logically break all suspend/resume operations into disctint RX and TX code paths. When the system enters S3, we will loose all register contents, so make sure that we correctly re-program all the hardware and software views of the RX & TX rings as well.

Quite often we need to enable either the transmitter or the receiver bits in UMAC_CMD, use umac_enable_set() to do that for us.

2014-07-07tlan: Isolate external PHY when using internal PHYOndrej Zary
When using internal 10 Mbps PHY, isolate the external PHY from MII bus. External PHY must be kept powered up because it passes TX from tlan chip to network. This fixes weird link-loss problems under load with OC-2326 card at 10 Mbps. Signed-off-by: Ondrej Zary <linux@rainbow-software.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2014-07-07tlan: Enable device at resumeOndrej Zary
pci_disable_device() is called in _suspend but there's no corresponding pci_enable_device() in _resume. This causes "disabling already-disabled device" warning on 2nd suspend.

2014-07-07tlan: Don't disable internal PHY on cards that use it in 10 Mbps modeOndrej Zary
In tlan_reset_adapter, we disable internal PHY when an external one is used. On cards which use internal PHY in 10 Mbps mode, we enable it later when setting 10 Mbps mode but it does not really work (PHY fails to reset). Leave it enabled instead.

2014-07-02be2net: create optimal number of queues on SR-IOV configVasundhara Volam
If SR-IOV is enabled in the adapter, the FW distributes queue resources evenly across the PF and it's VFs. If the user is not interested in enabling VFs, the queues set aside for VFs are wasted. This patch adds support for the PF driver to re-configure the resource distribution in FW based on the number of VFs enabled by the user. This also allows for supporting RSS queues on VFs, when less number of VFs are enabled per PF. When maximum number of VFs are enabled, each VF typically gets only one RXQ.

2014-07-01Merge branch 'master' of ↵David S. Miller
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-next Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2014-07-01 This series contains updates to i40e, i40evf, igb and ixgbe. Shannon adds the Base Address High and Low to the admin queue structure to simplify the logic in the configuration routines. Also adds code to clear all queues and interrupts to help clean up after a PXE or other early boot activity. Kevin fixes mask assignment value since -1 cannot be used for unsigned integer types. Mitch fixes an issue where in some circumstances the reply from the PF would come back before we were able to properly modify the admin queue pending and required flags. This would mess up the flags and put the driver in an indeterminate state, so fix this by simply setting the flags before sending the request to the admin queue. Also changes the branding string for i40evf to reduce confusion and to match up with our other marketing materials. Kamil adds a new variable defining admin send queue (ASQ) command write back timeout to allow for dynamic modification of this timeout. Anjali fix a bug in the flow director filter replay logic, so that we call a replay after a sideband reset correctly. Jesse adds code to initialize all members of the context descriptor to prevent possible stale data. Christopher fixes i40e to prevent writing to reserved bits, since the queue index is only 0-127. Jacob removes the unneeded header export.h from the i40e PTP code. Fixes ixgbe PTP code where the PPS signal was not correct, as it generates a one half HZ clock signal, it only generates one level change per second. To generate a full clock, we need two level changes per second. Todd provides a fix for igb to bring up link when the PHY has powered up, which was reported by Jeff Westfahl. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>

Use the firmware interface to get the BAR0 value since we really don't want to use the PCI-E Configuration Space Backdoor access which is owned by the firmware. Set up PCI-E Memory Window registers using the true values programmed into BAR registers. When the PF4 "Master Function" is exported to a Virtual Machine, the values returned by pci_resource_start() will be for the synthetic PCI-E Configuration Space and not the real addresses. But we need to program the PCI-E Memory Window address decoders with the real addresses that we're going to be using in order to have accesses through the Memory Windows work.

2014-07-01bnx2x: Fail probe of VFs using an old incompatible driverYuval Mintz
There are linux distributions where the inbox bnx2x driver contains SRIOV support but doesn't contain the changes introduced in b9871bcf "bnx2x: VF RSS support - PF side". A VF in a VM running that distribution over a new hypervisor will access incorrect addresses when trying to transmit packets, causing an attention in the hypervisor and making that VF inactive until FLRed. The driver in the VM has to ne upgraded [no real way to overcome this], but due to the HW attention currently arising upgrading the driver in the VM would not suffice [since the VF needs also be FLRed if the previous driver was already loaded]. This patch causes the PF to fail the acquire message from a VF running an old problematic driver; The VF will then gracefully fail it's probe preventing the HW attention [and allow clean upgrade of driver in VM].
