* ixgbe: Avoid needless PHY access on copper physMark Rustad2015-09-022-21/+44
| | | | | | | | | Avoid a needless PHY access on copper phys to save the 10ms wait time for each PHY access. A helper function is introduced to actually do the register access and process the contents.

* ixgbe: Remove second instance of lan_id variableDon Skidmore2015-09-022-4/+1
| | | | | | | | | | | | | This patch removes the redundant lan_id in the phy struct and uses the bus version. Both variables exist and intend to represent the STATUS register LAN_ID field. However, phy.lan_id is not bit shifted so the phy.lan_id = 0x0 for LAN Id 0 and phy.lan_id = 0x4 for LAN Id 1. Where bus.lan_id is bit shifted so bus.lan_id = 0x0 for LAN Id 0 and bus.lan_id = 0x1 for LAN Id 1. There seems no need for the additional lan_id variable and this should make the code less confusing.

* i40e: Set defport behavior for the Main VSI when in promiscuous modeAnjali Singhai Jain2015-09-022-8/+30
| | | | | | | | | | | | | | | | | | | | | This fixes bugs where the port is not receiving multicast or VLAN tagged packets when in promiscuous mode. This can occur when a SW bridge is created on top of the device. This also fixes issues where the promiscuous behavior setting was not being preserved across a reset caused by features being enabled or disabled. We are using defport instead of doing a true promiscuous mode because we do not need to receive the SRIOV or VMDq VSI directed traffic which would suck up bandwidth and is really not intended for the SW bridge. In addition, with defport we get VLAN promiscuous behavior which is not possible from the VSI level promiscuous setting.

* net: phy: fixed_phy: Set phy capabilities even when link down.Andrew Lunn2015-08-311-25/+48
| | | | | | | | | | | | | | | | | | | | What features a phy supports is masked in genphy_config_init() by looking at the PHYs BMSR register. If the link is down, fixed_phy_update_regs() will only set the auto- negotiation capable bit in BMSR. Thus genphy_config_init() comes to the conclusion the PHY can only perform 10/Half, and masks out the higher speed features. If however the link it up, BMSR is set to indicate the speed the PHY is capable of auto-negotiating, and genphy_config_init() does not mask out the high speed features. To fix this, when the link is down, have fixed_phy_update_regs() leave the link status, auto-negotiation complete, and link partner capabilities unset, but set all the local capabilities depending on the fixed phy speed.

There are however use cases where the CPU has a slower port, and when user ports have SFP modules with fixed speed. In these cases, port settings to be read from a fixed_phy devices.

* net: phy: Allow PHY devices to identify themselves as Ethernet switches, etc.Florian Fainelli2015-08-311-0/+1
| | | | | | | | | | | | | | | | | | | | | | | Some Ethernet MAC drivers using the PHY library require the hardcoding of link parameters when interfaced to a switch device, SFP module, switch to switch port, etc. This has typically lead to various ad-hoc implementations looking like this: - using a "fixed PHY" emulated device, which will provide link indication towards the Ethernet MAC driver and hardware - pretend there is no PHY and hardcode link parameters, ala mv643x_eth Based on that, it is desireable to have the PHY drivers advertise the correct link parameters, just like regular Ethernet PHYs towards their CPU Ethernet MAC drivers, however, Ethernet MAC drivers should be able to tell whether this link should be monitored or not. In the context of an Ethernet switch, SFP module, switch to switch link, we do not need to monitor this link since it should be always up.

| | | | | | | | | | | | | | | | | | | | | | | | Geneve can benefit from GRO at the device level in a manner similar to other tunnels, especially as hardware offloads are still emerging. After this patch, aggregated frames are seen on the tunnel interface. Single stream throughput nearly doubles in ideal circumstances (on old hardware).

| * | Bluetooth: hci_intel: Add support for platform driverLoic Poulain2015-08-281-13/+189
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | A platform device can be used to provide some specific resources in order to manage the controller. In this first patch we retrieve the reset gpio which is used to power on/off the controller. The main issue is to match the current tty with the correct pdev. In case of ACPI, we can easily find the right tty/pdev pair because they are both child of the same UART port. If controller is powered-on from the driver, we need to wait for a HCI boot event before being able to send any command.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Implement the set_baudrate callback for hci_intel. - Controller requires a read Intel version command before updating its baudrate. - The operation consists in an async cmd since the controller does not respond at the same speed. - Wait 100ms to let the controller change its baudrate. - Clear RTS until we change our own UART speed Manage speed change in the setup function, we need to restore the oper speed once chip has booted on patched firmware.

* | | vxlan: do not receive IPv4 packets on IPv6 socketJiri Benc2015-08-291-0/+1
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | By default (subject to the sysctl settings), IPv6 sockets listen also for IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in packets received through an IPv6 socket. In addition, it's currently not possible to have both IPv4 and IPv6 vxlan tunnel on the same port (unless bindv6only sysctl is enabled), as it's not possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's no way to specify both IPv4 and IPv6 remote/group IP addresses. Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not done globally in udp_tunnel, as l2tp and tipc seems to work okay when receiving IPv4 packets on IPv6 socket and people may rely on this behavior. The other tunnels (geneve and fou) do not support IPv6. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | There's currently nothing preventing directing packets with IPv6 encapsulation data to IPv4 tunnels (and vice versa). If this happens, IPv6 addresses are incorrectly interpreted as IPv4 ones. Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store this in ip_tunnel_info. Reject packets at appropriate places if they are supposed to be encapsulated into an incompatible protocol.
