There have been several changes since the first version of this code, so we bump the version number. While we're at it, we can simplify the version printing a bit and drop a couple lines of code. Signed-off-by:

The vio_dring_state *dr variable is unused in maybe_tx_wakeup(). As the comments indicate, we call maybe_tx_wakeup() whenever we get a STOPPED LDC message on the port. If the queue is stopped, we want to wake it up so that we will send another START message at the next TX and trigger the consumer to drain the dring. Signed-off-by:

When the sunvnet_common code was split out for use by both sunvnet and the newer ldmvsw, it was made into a static kernel library, which limits the usefulness of sunvnet and ldmvsw as loadables, since most of the real work is being done in the shared code. Also, this is simply dead code in kernels that aren't running the LDoms. This patch makes the sunvnet_common into a dynamically loadable module and makes sunvnet and ldmvsw dependent on sunvnet_common. Signed-off-by:

Edward Cree says: ==================== sfc: prevent bogus interrupt-mode fallbacks EF10 VFs only support MSI-X interrupts, not MSI or legacy. This series stops the probe logic from trying to fallback to those if MSI-X interrupt probe fails. It also prevents selecting them with the interrupt_mode module parameter. This avoids producing messages like "failed to hook legacy IRQ 0" and "IRQ handler type mismatch for IRQ 0", and ensures that the relevant error (from the attempt to enable MSI-X) is reported to the caller. ==================== Signed-off-by: -

Add min_interrupt_mode specification per NIC type. It is a bit confusing because of "highest interrupt mode is less capable". Signed-off-by:

Nikolay Aleksandrov says: ==================== bridge: minor fdb cleanup These patches aim to simplify the bridge fdb API a little by removing some redundant functions and converting them into wrappers of a single function. Also add proper lock checking to avoid future mistakes for the search functions. ==================== Signed-off-by: -
Nikolay Aleksandrov authored
We can simplify the logic of entries pointing to the bridge by converging the fdb_delete_by functions, this would allow us to use the same function for both cases since the fdb's dst is set to NULL if it is pointing to the bridge thus we can always check for a port match. Signed-off-by:

In order to avoid new errors add checks to br_fdb_find and fdb_find_rcu functions. The first requires hash_lock, the second obviously RCU. Signed-off-by:
-
Nikolay Aleksandrov authored
Before this patch we had 3 different fdb searching functions which was confusing. This patch reduces all of them to one - fdb_find_rcu(), and two flavors: br_fdb_find() which requires hash_lock and br_fdb_find_rcu which requires RCU. This makes it clear what needs to be used, we also remove two abusers of __br_fdb_get which called it under hash_lock and replace them with br_fdb_find(). Signed-off-by:

garp_port is only used in net/802/garp.c which is only compiled with CONFIG_GARP enabled. Same goes for mrp_port which is only used in net/802/mrp.c with CONFIG_MRP enabled. Only include the two members in struct net_device if their respective CONFIG_* is enabled. This saves a few bytes in struct net_device in case CONFIG_GARP or CONFIG_MRP are not enabled.

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2017-02-11 This series contains updates to i40e and i40evf only. Jake makes a minor change to prevent a minor bit of work, if it is not necessary. In the case where we do not have a client, there is no need to check the client params, so move the check till after we have ensured we have a client. Correct a code comment which incorrectly implied that raw_packet buffers were freed in i40e_clean_tx_ring(), so fixed the code comment to better explain where memory is freed. Reduce the severity and frequency of the message notifying we cleared the receive timestamp register, since the logic has a much better detection scheme that could detect a stalled receive timestamp register. The improved logic was actually causing the notification message to occur more frequently and was giving the user a false perception that a timestamp event was missed for a valid packet, so reduce the severity from dev_warn to dev_dbg and only fire off the message when 3 or 4 of the RXTIME registers are stalled and get cleared within the same watchdog event. Fixed a bug, where we were modifying the mac_filter outside a lock when handling the addition of broadcast filters. Fix this by updating i40e_update_filter_state logic so that it knows to avoid broadcast filters, which ensures that we do not have to remove the filter separately and can put it back using the normal flow. Refactored how we add new filters to firmware to avoid a race condition that can occur due to removing filters from the hash temporarily. Mitch adds a sleep (without timeout) so that we wait for a reply from the PF before we continue, since the iWarp client cannot continue until the operation is completed. Fixed up a function which could never return an error, to be void and cleaned up the checking of the now null and void return value. Scott limits the DMA sync to CPU to the actual length of the incoming packet, versus the syncing of the entire buffer. Also reduces the receive buffer struct (by a single pointer) and align the driver to be more consistent with other Intel drivers with respect to packets that span buffers. Sudheer adds a field to track the bus number info and modified log statements to print bus, device and function information. Henry adds the ability to store the FEC status bits from the link up event. Also adds the ethtool support for FEC capabilities and 25G link types. ==================== Signed-off-by:

Andrew Lunn says: ==================== mv88e6xxx Watchdog support The Marvell switches have an in built watchdog over some of the internal state machine. The watchdog can be configured to raise an interrupt on error. The problem the watchdog found is then logged to the kernel log. The older switches can automagically perform a software reset when the watchdog triggers. This just resets the internal state machine, but leaves the switch configuration unchanged. The 6390 family of switches cannot both raise an interrupt and automagically perform a software reset. So the interrupt handler has to perform the switch reset, and then re-enable the watchdog interrupts. This has been tested using hacked together debugfs code which allows the "force" bit to be set, so cause a watchdog interrupt. v2: Remove g2_prefix ==================== Signed-off-by: -

Andrew Lunn authored
The switch contains a watchdog looking for issues with the internal gubbins of the switch. Hook the interrupt the watchdog triggers and log the value of the control register indicating why the watchdog fired. The watchdog can only be cleared with a switch reset, which will destroy the current configuration. Rather than doing this, just disable the interrupt. The mv88e6390 family has different watchdog registers. So use an ops structure, so support for the mv88e6390 family can be added later. Signed-off-by:
