Aaron Brown says: ==================== Intel Wired LAN Driver Updates This series contains updates to i40e and i40evf, primarily reset handling / refactoring along with a fair amount of minor cleanup. Jesse fixes some spelling, bumps the version and other trivial fixes. Akeem sets a bit that is needed before shutdown in the case of tx_timeout recovery failure. Mitch refactors reset handling along with a whole bunch of clean up. ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

Respond better to a VF reset event. When a reset is signaled by the PF, or detected by the watchdog task, prevent the watchdog from processing admin queue requests, and schedule the reset task. In the reset task, wait first for the reset to start, then for it to complete, then reinit the driver. If the reset never appears to complete after a long, long time (>10 seconds is possible depending on what's going on with the PF driver), then set a flag to indicate that PF communications have failed. If this flag is set, check for the reset to complete in the watchdog, and attempt to do a full reinitialization of the driver from scratch. With these changes the VF driver correctly handles a PF reset event while running on bare metal, or in a VM. Also update copyrights.

As pointed out by Dan Carpenter (from Oracle), the flags variable is declared as a 64-bit long but all of the flags are defined as u32, which may lead to unintended consequences. Fix this by declaring flags as u32 (since we don't need any more than about a dozen flags right now), and remove the volatile qualifier, since it's unnecessary and just makes checkpatch cry.

Since we store the traffic vector names in the queue vector struct, we don't need to maintain an array of strings for these names in the adapter structure. Replace this array with a single string and use it when allocating the misc irq vector. Also update copyrights. Change-ID: I664f096c3c008210d6a04a487163e8aa934fee5b Signed-off-by:

Set the DOWN flag before attempting to disable VFs when unloading the driver. Also, don't attempt to reset the VFs when the driver is unloading, because the switch configuration will fail. This fixes a panic on unload when VFs are enabled. Change-ID: I25a6567e89c9687145f510ff4f630932412c5c5d Signed-off-by:

Reset all of the VFs after a PF reset, so that they are in a known state, and the VF driver can detect the reset and reinit itself. Change-ID: I93c5b3a0f8b1371d0da078f92de948b9d3a6413f Signed-off-by:

This looks like a cut and paste error. The code makes no sense where it is, and accomplishes nothing. Since we've removed the goto, we can also get rid of the extraneous brackets. Change-ID: I9315e3eafeee0a5713c94b0dc57b58b60a849124 Signed-off-by:

As politely pointed out by Dave Miller, calls to memset do not need a void pointer cast. Additionally, it is preferred to use sizeof(*the actual object) instead of sizeof(type). Change-ID: Id6a02429b7040111531f3865ea03fbe619167cb3 Signed-off-by:

Yuval Mintz says: ==================== bnx2x: Enhancements & semantic changes series This patch series contains several semantic (or mostly semantic) patches, as well as adding support for packet aggregations on the receive path of windows VMs and updating bnx2x to the new FW recently accepted upstream. Please consider applying these patches to `net-next'. (This is a repost as net-next was still closed when this was previously sent) ==================== Signed-off-by: -

This new firmware fixes following bugs: 1. HW attention appears and traffic stops when iSCSI firmware tries to retransmit iSCSI login command when the iSCSI login is carrying data not aligned to 4-bytes. 2. FCoE traffic fails to run when running in switch-independent multi-function mode and there's more than one interface supporting FCoE on a given port. 3. While two ports are running FCoE with at least one of them has a function number (>1) on the same engine in a 4-port device a zeroed CQE is given, causing FCoE traffic to stop.

bnx2x_panic_dump() prints all kind of driver information, including slowpath information. Since VFs don't initialize slowpath information, a VF reaching this flow will likely cause a panic in the system as it will access NULL pointers. Signed-off-by:

There are several places in IOV related flows where PF needs to determine whether a VF slowpath elements have already been configured (i.e., this affect its ability to configure/remove classifications for the VF). This patch changes the conditions for the validation and performs a cleaner validation (e.g., by replacing several validations with a single one). Signed-off-by:

of_get_phy_mode() uses a local array to map phy_interface_t values from include/linux/net/phy.h to a string which is read from the 'phy-mode' or 'phy-connection-type' property. In preparation for exposing the PHY interface mode through sysfs, perform the following: - mode phy_modes from drivers/of/of_net.c to include/linux/phy.h such that it is right below the phy_interface_t enum - make it a static inline function returning the string such that we can use it by just including include/linux/net/phy.h - add a PHY_INTERFACE_MODE_MAX enum value to guard the iteration in of_get_phy_mode() Signed-off-by:

Some PHYs out there can be very quirky with respect to how they would report the auto-negotiation is completed. Allow drivers to override the generic aneg_done() implementation by providing their own. Since not all drivers have been updated yet to use genphy_aneg_done() as aneg_done() callback, we explicitely check that this callback is valid before calling into it. Signed-off-by:

Florian Fainelli authored
In preparation for allowing PHY drivers to potentially override their auto-negotiation done callback, move the contents of phy_aneg_done() to genphy_aneg_done() since that function really is the generic implementation based on the BMSR_ANEGCOMPLETE status. Signed-off-by:
