2016-03-11macvtap: always pass ethernet header in linearWillem de Bruijn1-3/+6
The stack expects link layer headers in the skb linear section. Macvtap can create skbs with llheader in frags in edge cases: when (IFF_VNET_HDR is off or vnet_hdr.hdr_len < ETH_HLEN) and prepad + len > PAGE_SIZE and vnet_hdr.flags has no or bad csum. Add checks to ensure linear is always at least ETH_HLEN. At this point, len is already ensured to be >= ETH_HLEN. For backwards compatiblity, rounds up short vnet_hdr.hdr_len. This differs from tap and packet, which return an error. Fixes b9fb9ee07e67 ("macvtap: add GSO/csum offload support") Signed-off-by: Willem de Bruijn <[email protected]> Signed-off-by: David S.

2016-03-10net/mlx5e: Support offload cls_flower with skbedit mark actionAmir Vadai3-0/+6
Introduce offloading of skbedit mark action. For example, to mark with 0x1234, all TCP (ip_proto 6) packets arriving to interface ens9: # tc qdisc add dev ens9 ingress # tc filter add dev ens9 protocol ip parent ffff: \ flower ip_proto 6 \ indev ens9 \ action skbedit mark 0x1234 Signed-off-by: Amir Vadai <[email protected]> Signed-off-by: Or Gerlitz <[email protected]> Signed-off-by: David S.

2016-03-10net/mlx5e: Introduce tc offload supportAmir Vadai5-2/+222
Extend ndo_setup_tc() to support ingress tc offloading. Will be used by later patches to offload tc flower filter. Feature is off by default and could be enabled by issuing: # ethtool -K eth0 hw-tc-offload on Offloads flow table is dynamically created when first filter is added. Rules are saved in a hash table that is maintained by the consumer (for example - the flower offload in the next patch). When last filter is removed and no filters exist in the hash table, the offload flow table is destroyed.

2016-03-10net-next: mediatek: add support for MT7623 ethernetJohn Crispin2-0/+2228
Add ethernet support for MediaTek SoCs from the MT7623 family. These have dual GMAC. Depending on the exact version, there might be a built-in Gigabit switch (MT7530). The core does not have the typical DMA ring setup. Instead there is a linked list that we add descriptors to. There is only one linked list that both MACs use together. There is a special field inside the TX descriptors called the VQID. This allows us to assign packets to different internal queues. By using a separate id for each MAC we are able to get deterministic results for BQL. Additionally we need to provide the core with a block of scratch memory that is the same size as the RX ring and data buffer. This is really needed to make the HW datapath work. Although the driver does not support this yet, we still need to assign the memory and tell the core about it for RX to work.

2016-03-10qlcnic: Fix mailbox completion handling during spurious interruptRajesh Borundia3-5/+14
o While the driver is in the middle of a MB completion processing and it receives a spurious MB interrupt, it is mistaken as a good MB completion interrupt leading to premature completion of the next MB request. Fix the driver to guard against this by checking the current state of MB processing and ignore the spurious interrupt. Also added a stats counter to record this condition.

2016-03-10cxgb4vf: Configure queue based on resource and interrupt typeHariprasad Shenai1-71/+94
The Queue Set Configuration code was always reserving room for a Forwarded interrupt Queue even in the cases where we weren't using it. Figure out how many Ports and Queue Sets we can support. This depends on knowing our Virtual Function Resources and may be called a second time if we fall back from MSI-X to MSI Interrupt Mode. This change fixes that problem.

2016-03-10cxgb4vf: Enable interrupts before we register our network devicesHariprasad Shenai1-25/+26
This avoids a race condition where a system that has network devices set up to be automatically configured and we get the first Port Link Status message from the firmware on the Asynchronous Firmware Event Queue before we've enabled interrupts. If that happens, we end up losing the interrupt and never realizing that the links has actually come up. Signed-off-by: Hariprasad Shenai <[email protected]> Signed-off-by: David S.

2016-03-10sh_eth: advance 'rxdesc' later in sh_eth_ring_format()Sergei Shtylyov1-3/+4
Iff dma_map_single() fails, 'rxdesc' should point to the last filled RX descriptor, so that it can be marked as the last one, however the driver would have already advanced it by that time.

2016-03-10net/mlx5_core: Introduce forward to next priority actionMaor Gottlieb2-12/+182
Add support to create flow rule that forward packets to the first flow table in the next priority (next priority could be the first priority in the next namespace or the next priority in the same namespace). This feature could be used for DONT_TRAP rules or rules that only want to mark the packet with flow tag. In order to do it optimally, each flow table has list of all rules that point to this flow table, when a flow table is destroyed/created, we update the list head correspondingly. This kind of rule is created when destination is NULL and action is MLX5_FLOW_CONTEXT_ACTION_FWD_NEXT_PRIO.
