pci_enable_msix has been long deprecated, but this driver adds a new instance. Convert it to pci_alloc_irq_vectors so that no new instance of the deprecated function reaches mainline. Signed-off-by:

Yuval Mintz says: ==================== qed*: Add support for PTP This patch series adds required changes for qed/qede drivers for supporting the IEEE Precision Time Protocol (PTP). Changes from previous versions: v7: Fixed Kbuild robot warnings. v6: Corrected broken loop iteration in previous version. Reduced approximation error of adjfreq. v5: Removed two divisions from the adjust-frequency loop. Resulting logic would use 8 divisions [instead of 24]. v4: Remove the loop iteration for value '0' in the qed_ptp_hw_adjfreq() implementation. v3: Use div_s64 for 64-bit divisions as do_div gives error for signed types. Incorporated review comments from Richard Cochran. - Clear timestamp resgisters as soon as timestamp is read. - Use shift operation in the place of 'divide by 16'. v2: Use do_div for 64-bit divisions. ==================== Acked-by:Richard Cochran <richardcochran@gmail.com> Signed-off-by:

Commit 91572088 ("net: use core MTU range checking in core net infra") changed the openvswitch internal device to use the core net infra for controlling the MTU range, but failed to actually set the max_mtu as described in the commit message, which now defaults to ETH_DATA_LEN. This patch fixes this by setting max_mtu to ETH_MAX_MTU after ether_setup() call. Fixes: 91572088 ("net: use core MTU range checking in core net infra") Signed-off-by:

Using a reader-writer lock in fast path is silly, when we can instead use RCU or a seqlock. For mlx4 hwstamp clock, a seqlock is the way to go, removing two atomic operations and false sharing. Signed-off-by:

The usage count function is based on ndev_running flag that is updated before calling ndo_open/close, but if ndo is called in another place, as with suspend/resume, the counter is not changed, that breaks sus/resume. For common resource no difference which device is using it, does matter only device count. So, replace usage count function on var and inc and dec it in ndo_open/close. Signed-off-by:

Even though the port autoselection is enabled by default on AM79C970A, BNC/AUI port does not work because the link is always reported to be down. The link state reported by the chip belongs only to the TP port but the driver uses it regardless of the port used. The chip can't detect BNC/AUI link state. Disable port autoselection and use TP port by default to keep current behavior (link detection works on TP port, BNC/AUI port does not work). Implement ethtool autoneg, port and duplex configuration to allow using the BNC/AUI port. Report the TP link state only if the TP port is selected. When the port autoselection is enabled or AUI port is selected, report the link as always up. Move pcnet32_suspend() and pcnet32_clr_suspend() functions to avoid forward declarations. Signed-off-by:

Shannon Nelson says: ==================== sunvnet driver updates The sunvnet ldom virtual network driver was due for some updates and a bugfix or two. These patches address a few items left over from last year's make-over. v2: - changed memory barrier fix to use smp_wmb - put NETIF_F_SG back into the advertised ldmvsw hw_features v3: - the sunvnet_common module doesn't need module_init or _exit v4: - dropped the statistics patch - fixed up "default" tag for SUNVNET_COMMON ==================== Signed-off-by: -
Shannon Nelson authored
The ldmvsw driver is specifically for supporting the ldom virtual networking by running in the primary ldom and using the LDC to connect the remaining ldoms to the outside world via a bridge. With TSO and GSO supported while connected the bridge, things tend to misbehave as seen in our case by delayed packets, enough to begin triggering retransmits and affecting overall throughput. By turning off advertised support for TSO and GSO we restore stable traffic flow through the bridge. Orabug: 23293104 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: -

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:

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:
