* i40e: fix netdev_stat macro definitionShannon Nelson2014-12-061-1/+2
| | | | | | | | | | | | The old xxx_NETDEV_STAT() macro was defined long before the newer rtnl_link_stats64 came into being, and just never got updated. Since we're using rtnl_link_stats64 in other parts of the driver, we should use it here as well. We've just been lucky that the field definitions are the same sizes.

* i40e: don't enable PTP support on more than one PF per portJacob Keller2014-12-062-11/+25
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Resolve an issue related to images with multiple PFs per physical port. We cannot fully support 1588 PTP features, since only one port should control (ie: write) the registers at a time. Doing so can cause interference of functionality. It may be possible to partially implement the API for only those features without side effects. However, this at minimum means non controlling PFs lose Tx timestamps, frequency atunement, and possibly SYSTIME adjustment. There may be further impact I did not discover. Since the API in the kernel expects these features to work, it is simpler and less dangerous to just disable PTP features on all PFs not identified as the controlling PF in PRTTSYN_CTL0.PF_ID. This change also removes the warning printed when hwtstaml IOCTL is called on the wrong PF. This is actually meaningless now, since only one PF per port will support it. In addition, the ethtool get_ts_info IOCTL was updated so that only the controlling port will even indicate support (so as not to confuse users). The overall downside is complete loss of functionality on non controlling PF, vs the possible gain of partial support. The biggest factor for choosing this approach is simplicity and ensuring that the main PF will work. There could easily be other portions of the 1588 logic with side effects I am not aware, and the reduced functionality that might be made available is significantly less useful. In addition, the API does not allow for proper indication of why particular features are not supported. These reasons are enough to decide for the simpler approach to resolving this issue.

| | | | | | | | | | | | | | | | | | | | This patch cleans up the page reuse code getting it into a state where all the workarounds needed are in place as well as cleaning up a few minor oversights such as using __free_pages instead of put_page to drop a locally allocated page. It also cleans up how we clear the descriptor status bits. Previously they were zeroed as a part of clearing the hdr_addr. However the hdr_addr is a 64 bit field and 64 bit writes can be a bit more expensive on on 32 bit systems. Since we are no longer using the header split feature the upper 32 bits of the address no longer need to be cleared. As a result we can just clear the status bits and leave the length and VLAN fields as-is which should provide more information in debugging.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | Add L2 bridge offloading support to rocker driver. Here, the Linux bridge driver is used to collect swdev ports into a tagged (or untagged) VLAN bridge. The switchdev will offload from the bridge driver the following L2 bridging functions: - Learning of neighbor MAC addresses on VLAN X Learned mac/vlan is installed in bridge FDB. (And removed when device unlearns mac/vlan). Learning must be turned off on each bridge port to disable the feature in the bridge driver. - Flooding of multicast/broadcast and unknown unicast pkts to (STP) active ports in bridge. The bridge driver is unaware of the flooding happening at the device level. Flooding must be turned off on each bridge port to disable the feature on the bridge driver. - STP port state is pushed down to driver/device. The bridge still processes STP BDPUs and maintains port STP state (for all VLANs in bridge), but the driver/device must be notified of port STP state change to program the device. Multiple (VLAN) bridges are supported. The device (implemented per the OF-DPA spec) must use a portion of the VLAN namespace for internal VLANs. Right now, the upper 255 VLANs (0xf00 to 0xffe) are used as internal VLAN IDs for untagged traffic and are not available as port VLANs. The driver uses the following interfaces: 1. To track VLAN add/del on ports in bridge: .ndo_vlan_rx_add_vid .ndo_vlan_rx_kill_vid 2. To track port add/del membership in bridge: NETDEV_CHANGEUPPER netdevice notifier 3. To catch static FDB entries installed on bridge/vlan by user using netlink: .ndo_fdb_add .ndo_fdb_del 4. To be notified on port STP state change: .ndo_switch_port_stp_update 5.

* rocker: implement rocker ofdpa flow table manipulationScott Feldman2014-12-031-2/+1467
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The rocker driver maintains 4 hash tables: flows, groups, FDB, and VLANs. Flow and group tables track the entries installed to OF-DPA tables, per the OF-DPA spec. See OF-DPA spec for full description of fields in each flow and group table. New table entries are pushed to the device with ADD cmd. Updated entries are pushed to the device with MOD cmd. For flow table entries, a crc32 key is made from fields of the particular field. For group table entries, the group_id is used as the key. The FDB table tracks fdb entries learned by the device or manually pushed to the bridge by the user. A crc32 key is made from the port/mac/vlan tuple for the fdb entry. The VLAN table tracks the ifindex-to-internal-vlan mapping for untagged pkts. On ingress, an untagged pkt is inserted with an internal VLAN ID based on the input port's current internal VLAN ID. The input port's internal VLAN will either be referenced by the port's ifindex, if not bridged, or the containing bridge's ifindex, if bridged. Since the ifindex space isn't within a fixed range, uses a hash table (with ifindex as key) to track internal VLAN ID for a given ifindex. The internal VLAN ID range is fixed and currently uses the upper 255 VLAN IDs, starting at 0xf00.

| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The existing order of steps when starting the PCI devices works for 2.4G devices, but fails to initialize the 5G section of the RTL8821AE hardware. This patch is needed to fix the regression reported in Bug #88811 (https://bugzilla.kernel.org/show_bug.cgi?id=88811).

| * | | net/mlx4_core: Limit count field to 24 bits in qp_alloc_resJack Morgenstein2014-11-261-1/+1

Under the current code, if any of these flags are set, the 32-bit count field yields a count greater than 2^24, which is out of range, and this VF fails. As these flags represent a "best-effort" allocation hint anyway, they may safely be ignored. Therefore, the PF driver may simply mask out the bits.
