2017-02-15mlxsw: acl: Use PBS type for forward actionJiri Pirko1-11/+9
Current behaviour of "mirred redirect" action (forward) offload is a bit odd. For matched packets the action forwards them to the desired destination, but it also lets the packet duplicates to go the original way down (bridge, router, etc). That is more like "mirred mirror". Fix this by using PBS type which behaves exactly like "mirred redirect". Note that PBS does not support loopback mode.

2017-02-14pcnet32: fix BNC/AUI port on AM79C970AOndrej Zary1-52/+125
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.

2017-02-14ldmvsw: disable tso and gso for bridge operationsShannon Nelson2-4/+4
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: Shannon Nelson <shannon.nelson@oracle.com> Signed-off-by: David S.

2017-02-14sunvnet: make sunvnet common code dynamically loadableShannon Nelson2-2/+11
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.

2017-02-14Merge branch '40GbE' of ↵David S. Miller17-285/+463
git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue 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: David S.
