Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2016-01-08 This series contains updates to i40e and i40evf only. Mitch adds a useful error message and return value when the VFs are being reset, since there is a brief window of time when the VF cannot be configured because they do not have a VSI to configure. Also made a driver change to allow the user to specify a zero MAC address for VFs, which causes the existing MAC address to be removed and allows the VF to use a random address (like libvirt). Sowmini Varadhan from Oracle adds similar functionality/fix to i40e that was added to ixgbe earlier. The fix attempts to look up the MAC address in the Open Firmware on systems that support it and use IDPROM on SPARC if no OF address is found. Anjali provides a fix the code path so that we do not call skb_set_hash() if the feature is disabled. Jesse removes a device ID that has never been productized and there are no plans to use it, so just remove it. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Somehow an ID that has never been productized is in the code. There are no plans to use it, so just get rid of it. Change-ID: I59117d48ea9ee0360b0fe33833ac8092f8a24b4c Signed-off-by:

If the driver calls skb_set_hash even with a zero hash, that indicates to the stack that the hash calculation is offloaded in hardware. So the Stack doesn't do a SW hash which is required for load balancing if the user decides to turn of rx-hashing on our device. This patch fixes the path so that we do not call skb_set_hash if the feature is disabled. Change-ID: Ic4debfa4ff91b5a72e447348a75768ed7a2d3e1b Signed-off-by:

This is the i40e equivalent of commit c762dff2 ("ixgbe: Look up MAC address in Open Firmware or IDPROM"). As with that fix, attempt to look up the MAC address in Open Firmware on systems that support it, and use IDPROM on SPARC if no OF address is found. In the case of the i40e there is an assumption that the default mac address has already been set up as the primary mac filter on probe, so if this filter is obtained from the Open Firmware or IDPROM, an explicit write is needed via i40e_aq_mac_address_write() and i40e_aq_add_macvlan() invocation. The I40E_FLAG_PF_MAC flag in the platform-private i40e_pf structure tracks whether a platform-specific mac address was found, in which case calls to i40e_aq_mac_address_write() and i40e_aq_add_macvlan() will be triggered.

Allow the user to specify a zero MAC address for VFs. This removes the existing MAC address and allows the VF to use a random address. Libvirt does this normally when removing a VF from a VM. Signed-off-by:

When VFs are being reset, there is a brief window of time when they cannot be configured because they don't have a VSI to configure. If a script is quick, it can fall through that window. To avoid defenestration, log a useful error message and return -EAGAIN. Signed-off-by:

Neil Armstrong says: ==================== Add new capability and macb DT variant The first patch introduces a new capability bit to disable usage of the USRIO register on platform not implementing it thus avoiding some external imprecise aborts on ARM based platforms. The two last patchs adds a new macb variant compatible name using the capability, the NP4 SoC uses this particular hardware configuration. v1: http://lkml.kernel.org/r/1449485914-12883-1-git-send-email-narmstrong@baylibre.com v2: http://lkml.kernel.org/r/1449582726-6148-1-git-send-email-narmstrong@baylibre.com v3: http://lkml.kernel.org/r/1451898103-21868-1-git-send-email-narmstrong@baylibre.com v4: http://lkml.kernel.org/r/1451900573-22657-1-git-send-email-narmstrong@baylibre.com v5: switch SoC name to non-generic NP4 name ==================== Signed-off-by:

Neil Armstrong authored
On some platforms, the macb integration does not use the USRIO register to configure the (R)MII port and clocks. When the register is not implemented and the MACB error signal is connected to the bus error, reading or writing to the USRIO register can trigger some Imprecise External Aborts on ARM platforms.

Andrew Lunn says: ==================== Support MDIO devices The discussions about changing the way DSA probes switches resulted in the wish to have switches attached to an MDIO bus to be represented as an MDIO device. However the current code only supports PHYs on MDIO busses. This patchset remedies this problem. It consists of a number of cleanups, abstraction for accessing structure members, and refactoring, as well as adding the concept of a generic MDIO device and MDIO driver. v2: Added Reviewed-by from Florian Made phydev_name() an inline function Added phy_attached_info/phy_attached_print() for information about the attached phy. Removed now redundant irq setup from of_mdio.c Dropped hunks from PHYMII ioctl which prevented access to any address DSA carrier off before phy setup ==================== Signed-off-by: -

Make it clear that mdiobus_scan () will only find devices which have a vendor/product ID in registers 2 and 3. These are typically PHY devices. Other sort of MDIO devices, such as switches, are not expected to be found during the scan. Similarly, __mdiobus_register(), which calls mdiobus_scan() will only find PHY devices, and other sorts of MDIO devices are expected to be instantiated from device tree. Signed-off-by:

The mdio_bus exports three attributes: - PHY ID is the unique 32-bits identifier for a MDIO device implementing standard MII registers MII_PHYSID1/2, which is not guaranteed to be the case for non-standard compliant devices (e.g: Ethernet switches) - PHY interface describes the data-path of the PHY/MDIO device, which is not strictly a PHY thing, but is required and needed for PHY devices to function, a MDIO device could be a control device exclusively - PHY has fixups describes what the PHY driver may have done, so completely PHY specific These are all phy attributes, not generic mdio attributes. So move the attributes into the phy device code. Signed-off-by:

Patch 3759824d ("tcp: PRR uses CRB mode by default and SS mode conditionally") introduced a bug that cwnd may become 0 when both inflight and sndcnt are 0 (cwnd = inflight + sndcnt). This may lead to a div-by-zero if the connection starts another cwnd reduction phase by setting tp->prior_cwnd to the current cwnd (0) in tcp_init_cwnd_reduction(). To prevent this we skip PRR operation when nothing is acked or sacked. Then cwnd must be positive in all cases as long as ssthresh is positive: 1) The proportional reduction mode inflight > ssthresh > 0 2) The reduction bound mode a) inflight == ssthresh > 0 b) inflight < ssthresh sndcnt > 0 since newly_acked_sacked > 0 and inflight < ssthresh Therefore in all cases inflight and sndcnt can not both be 0. We check invalid tp->prior_cwnd to avoid potential div0 bugs. In reality this bug is triggered only with a sequence of less common events. For example, the connection is terminating an ECN-triggered cwnd reduction with an inflight 0, then it receives reordered/old ACKs or DSACKs from prior transmission (which acks nothing). Or the connection is in fast recovery stage that marks everything lost, but fails to retransmit due to local issues, then receives data packets from other end which acks nothing.

A repeating pattern in drivers has become to use OF node information and, if not found, platform specific host information to extract the ethernet address for a given device. Currently this is done with a call to of_get_mac_address() and then some ifdef'd stuff for SPARC. Consolidate this into a portable routine, and provide the arch_get_platform_mac_address() weak function hook for all architectures to implement if they want. Signed-off-by: -
