2015-07-23ixgbevf: add support for reporting RSS key and hash table for X550Emil Tantilov
This patch extends the reporting of the RSS key and hash table by adding support for X550 VFs. The difference is that X550 VFs have their own registers for RSS key and indirection table, so there is no need to query the PF. The RSS key and indirection table are stored in the adapter structure during the configuration of VFRSSRK and VFRETA which in turn can be used in ethtool for reporting. The logic for writing VFRETA is also changed to make sure that the indirection table is reported correctly. In addition this patch adds defines for the VFRETA entries and number of VFRSSRK registers as well as some whitespace cleanups.

2015-07-21ravb: fix ring memory allocationSergei Shtylyov
The driver is written as if it can adapt to a low memory situation allocating less RX skbs and TX aligned buffers than the respective RX/TX ring sizes. In reality though the driver would malfunction in this case. Stop being overly smart and just fail in such situation -- this is achieved by moving the memory allocation from ravb_ring_format() to ravb_ring_init(). We leave dma_map_single() calls in place but make their failure non-fatal by marking the corresponding RX descriptors with zero data size which should prevent DMA to an invalid addresses.

2015-07-21sfc: support cascaded multicast filtersDaniel Pieczko
If the workaround to support cascaded multicast filters ("workaround_26807") is enabled, the broadcast filter and individual multicast filters are not inserted when in promiscuous or allmulti mode. There is a race while inserting and removing filters when entering and leaving promiscuous mode. When changing promiscuous state with cascaded multicast filters, the old multicast filters are removed before inserting the new filters to avoid duplicating packets; this can lead to dropped packets until all filters have been inserted. The efx_nic:mc_promisc flag is added to record the presence of a multicast promiscuous filter; this gives a simple way to tell if the promiscuous state is changing.

2015-07-21sfc: Insert multicast filters as well as mismatch filters in promiscuous modeJon Cooper
If a function is in promiscuous mode and another function has a broadcast or multicast filter inserted, the function in promiscuous mode won't see that broadcast or multicast traffic. Most notably this breaks broadcast, which means ARP doesn't work. Less show-stoppingly, a function listening on a multicast address that's also in promiscuous mode will not see that multicast traffic if another function is also listening on that multicast address.

2015-07-21sfc: warn if other functions have been reset by MCFWDaniel Pieczko
When enabling the workaround for cascaded multicast filters, the MC can reset other functions if they have already inserted filters. In that case, the workaround has been enabled, but print an info message in the log recording that other functions had to be reset. As other functions were reset, the MC will have incremented its boot count, so also increment the warm_boot_count on the function which enabled the workaround, as that function won't have received an MC reboot event and does not need to reset.

The nic_data->workaround_26807 will be used in the future to control the filter insertion behaviour based on this workaround. Only the primary PF can enable this workaround, so tolerate an EPERM error and continue. Otherwise, if any step in the checking and enabling of the workaround fails, the event queue must be removed.

The commit 898b2970e2c9 ("mvneta: implement SGMII-based in-band link state signaling") implemented the link parameters auto-negotiation unconditionally. Unfortunately it appears that some HW that implements SGMII protocol, doesn't generate the inband status, so it is not possible to auto-negotiate anything with such HW. This patch enables the auto-negotiation only if explicitly requested with the 'managed' DT property.

2015-07-21net: phy: fixed_phy: handle link-down caseStas Sergeev
fixed_phy_register() currently hardcodes the fixed PHY link to 1, and expects to find a "speed" parameter to provide correct information towards the fixed PHY consumer. In a subsequent change, where we allow "managed" (e.g: (RS)GMII in-band status auto-negotiation) fixed PHYs, none of these parameters can be provided since they will be auto-negotiated, hence, we just provide a zero-initialized fixed_phy_status to fixed_phy_register() which makes it fail when we call fixed_phy_update_regs() since status.speed = 0 which makes us hit the "default" label and error out. Without this change, we would also see potentially inconsistent speed/duplex parameters for fixed PHYs when the link is DOWN.

2015-07-21net: dsa: bcm_sf2: Do not override speed settingsFlorian Fainelli
The SF2 driver currently overrides speed settings for its port configured using a fixed PHY, this is both unnecessary and incorrect, because we keep feedback to the hardware parameters that we read from the PHY device, which in the case of a fixed PHY cannot possibly change speed. This is a required change to allow the fixed PHY code to allow registering a PHY with a link configured as DOWN by default and avoid some sort of circular dependency where we require the link_update callback to run to program the hardware, and we then utilize the fixed PHY parameters to program the hardware with the same settings.

2015-07-21vxlan: Flow based tunnelingThomas Graf
Allows putting a VXLAN device into a new flow-based mode in which skbs with a ip_tunnel_info dst metadata attached will be encapsulated according to the instructions stored in there with the VXLAN device defaults taken into consideration. Similar on the receive side, if the VXLAN_F_COLLECT_METADATA flag is set, the packet processing will populate a ip_tunnel_info struct for each packet received and attach it to the skb using the new metadata dst. The metadata structure will contain the outer header and tunnel header fields which have been stripped off. Layers further up in the stack such as routing, tc or netfitler can later match on these fields and perform forwarding. It is the responsibility of upper layers to ensure that the flag is set if the metadata is needed. The flag limits the additional cost of metadata collecting based on demand. This prepares the VXLAN device to be steered by the routing and other subsystems which allows to support encapsulation for a large number of tunnel endpoints and tunnel ids through a single net_device which improves the scalability. It also allows for OVS to leverage this mode which in turn allows for the removal of the OVS specific VXLAN code. Because the skb is currently scrubed in vxlan_rcv(), the attachment of the new dst metadata is postponed until after scrubing which requires the temporary addition of a new member to vxlan_metadata. This member is removed again in a later commit after the indirect VXLAN receive API has been removed.

It is okay to support the specific filters in SIOCSHWTSTAMP by upscaling them to the generic filters. Alex Duyck provides a igb patch to pull the time stamp from the fragment before it gets added to the skb, to avoid a possible issue in which the fragment can possibly be less than IGB_RX_HDR_LEN due to the time stamp being pulled after the copybreak check. Also provides a ixgbevf patch to fold the ixgbevf_pull_tail() call into ixgbevf_add_rx_frag(), which gives the advantage that the fragment does not have to be modified after it is added to the skb. Fan provides patches for ixgbe/ixgbevf to set the receive hash type based on receive descriptor RSS type.

We are currently doing a full PHY initialization and even starting the pHY state machine during bcmgenet_mii_init() which is executed in the driver's probe function. This is convenient to determine whether we can attach to a proper PHY device but comes at the expense of spending up to 10ms per MDIO transactions (to reach the waitqueue timeout), which slows things down. This also creates a sitaution where we end-up attaching twice to the PHY, which is not quite correct either. Fix this by moving bcmgenet_mii_probe() into bcmgenet_open() and update its error path accordingly. Avoid printing the message "attached PHY at address 1 [...]" every time we bring up/down the interface and remove this print since it duplicates what the PHY driver already does for us.

If the PHY is powered down, it will not respond to the MDIO bus, so we will not be able to bind a driver to it. Our Device Tree for GENET interfaces specifies a "phy-mode" value: "internal" which tells if this internal uses an internal PHY or not. If of_get_phy_mode() fails to parse the 'phy-mode' property, do an additional manual lookup, and if we find "internal" set the corresponding internal variable accordingly. Replace all uses of phy_is_internal() with a check against priv->internal_phy to avoid having to rely on whether or not priv->phydev is set correctly.

2015-07-20net: bcmgenet: Power on integrated GPHY in bcmgenet_power_up()Florian Fainelli
We are currently disabling the GPHY interface during bcmgenet_close(), and attempting to power it back on during bcmgenet_open(). This works fine for the first time, because we called bcmgenet_mii_config() which took care of enabling the interface, however, bcmgenet_power_up() really needs to power on the GPHY for correctness. This will be particularly important as we want to move bcmgenet_mii_probe() down to bcmgenet_open() to avoid seeing the "PHY already attached" message.

bcmgenet_open()'s error path call free_irq() with a dev_id argument different from the one we used to call request_irq() with, this will make us trip over the warning in kernel/irq/manage.c:__free_irq() Fixes: 1c1008c793fa4 ("net: bcmgenet: add main driver file") Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2015-07-20net: bcmgenet: Remove excessive PHY resetFlorian Fainelli
We are currently issuing multiple PHY resets during a suspend/resume, first during bcmgenet_power_up() which does a hardware reset, then a software reset by calling bcmgenet_mii_reset(). This is both unnecessary and can take as long as 10ms per MDIO transactions while we re-apply workarounds because we do not yet have MDIO interrupts enabled. phy_resume() takes care of re-apply our workarounds in case we need any, and bcmgenet_power_up() does a PHY hardware reset, all of this is more than enough to guarantee that the PHY operates correctly.

2015-07-20stmmac: add proper probe function to dwmac-mesonJoachim Eastwood
By using a few functions from stmmac_platform we can now create a proper probe function in this driver. By doing so we can drop the OF match data and simplify the overall driver. Signed-off-by: Joachim Eastwood <manabian@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>
