2015-08-30net: thunderx: Support for internal loopback modeSunil Goutham
Support for setting VF's corresponding BGX LMAC in internal loopback mode. This mode can be used for verifying basic HW functionality such as packet I/O, RX checksum validation, CQ/RBDR interrupts, stats e.t.c. Useful when DUT has no external network connectivity. 'loopback' mode can be enabled or disabled via ethtool. Note: This feature is not supported when no of VFs enabled are morethan no of physical interfaces i.e active BGX LMACs Signed-off-by: Sunil Goutham <sgoutham@cavium.com> Signed-off-by: Aleksey Makarov <aleksey.makarov@caviumnetworks.com> Signed-off-by: David S.

2015-08-30net: thunderx: Support for upto 96 queues for a VFSunil Goutham
This patch adds support for handling multiple qsets assigned to a single VF. There by increasing no of queues from earlier 8 to max no of CPUs in the system i.e 48 queues on a single node and 96 on dual node system. User doesn't have option to assign which Qsets/VFs to be merged. Upon request from VF, PF assigns next free Qsets as secondary qsets. To maintain current behavior no of queues is kept to 8 by default which can be increased via ethtool. If user wants to unbind NICVF driver from a secondary Qset then it should be done after tearing down primary VF's interface.

2015-08-30net: thunderx: Rework interrupt handlingSunil Goutham
Rework interrupt handler to avoid checking IRQ affinity of CQ interrupts. Now separate handlers are registered for each IRQ including RBDR. Register interrupt handlers for only those which are being used. Add nicvf_dump_intr_status() and use it in irq handlers.

2015-08-30net: thunderx: Support for HW VLAN strippingSunil Goutham
This patch configures HW to strip 802.1Q header if found in a receiving packet. The stripped VLAN ID and TCI information is passed on to software via CQE_RX. Also sets netdev's 'vlan_features' so that other HW offload features can be used for tagged packets. This offload feature can be enabled or disabled via ethtool. Network stack normally ignores RPS for 802.1Q packets and hence low throughput. With this offload enabled throughput for tagged packets will be almost same as normal packets. Note: This patch doesn't enable HW VLAN insertion for transmit packets.

2015-08-30net: thunderx: Receive hashing HW offload supportSunil Goutham
Adding support for receive hashing HW offload by using RSS_ALG and RSS_TAG fields of CQE_RX descriptor. Also removed dependency on minimum receive queue count to configure RSS so that hash is always generated. This hash is used by RPS logic to distribute flows across multiple CPUs. Offload can be disabled via ethtool.

2015-08-30cxl: Fix force unmapping mmaps of contexts allocated through the kernel apiIan Munsie
The cxl user api uses the address_space associated with the file when we need to force unmap all cxl mmap regions (e.g. on eeh, driver detach, etc). Currently, contexts allocated through the kernel api do not do this and instead skip the mmap invalidation, potentially allowing them to poke at the hardware after such an event, which may cause all sorts of trouble. This patch allocates an address_space for cxl contexts allocated through the kernel api so that the same invalidate path will for these contexts as well. We don't use the anonymous inode's address_space, as doing so could invalidate any mmaps of completely unrelated drivers using anonymous file descriptors. This patch also introduces a kernelapi flag, so we know when freeing the context if the address_space was allocated by us and needs to be freed.

2015-08-30cxl: Fix + cleanup error paths in cxl_dev_context_initIan Munsie
If the cxl_context_alloc() call fails, we return immediately without releasing the reference on the AFU device, allowing it to leak. This patch switches to using goto style error handling so that the device is released in common code for both error paths, and will also simplify things if we add additional initialisation in this function in the future.

2015-08-29geneve: Use GRO cells infrastructure.Jesse Gross
Geneve can benefit from GRO at the device level in a manner similar to other tunnels, especially as hardware offloads are still emerging. After this patch, aggregated frames are seen on the tunnel interface. Single stream throughput nearly doubles in ideal circumstances (on old hardware).

2015-08-29net/smsc911x: Fix deferred probe for interruptTony Lindgren
The interrupt handler may not be available when smsc911x probes if the interrupt handler is a GPIO controller for example. Let's fix that by adding handling for -EPROBE_DEFER.

2015-08-29vxlan: do not receive IPv4 packets on IPv6 socketJiri Benc
By default (subject to the sysctl settings), IPv6 sockets listen also for IPv4 traffic. Vxlan is not prepared for that and expects IPv6 header in packets received through an IPv6 socket. In addition, it's currently not possible to have both IPv4 and IPv6 vxlan tunnel on the same port (unless bindv6only sysctl is enabled), as it's not possible to create and bind both IPv4 and IPv6 vxlan interfaces and there's no way to specify both IPv4 and IPv6 remote/group IP addresses. Set IPV6_V6ONLY on vxlan sockets to fix both of these issues. This is not done globally in udp_tunnel, as l2tp and tipc seems to work okay when receiving IPv4 packets on IPv6 socket and people may rely on this behavior. The other tunnels (geneve and fou) do not support IPv6. Signed-off-by: Jiri Benc <jbenc@redhat.com> Signed-off-by: David S. Miller <davem@davemloft.net>
2015-08-29ip_tunnels: record IP version in tunnel infoJiri Benc
There's currently nothing preventing directing packets with IPv6 encapsulation data to IPv4 tunnels (and vice versa). If this happens, IPv6 addresses are incorrectly interpreted as IPv4 ones. Track whether the given ip_tunnel_key contains IPv4 or IPv6 data. Store this in ip_tunnel_info. Reject packets at appropriate places if they are supposed to be encapsulated into an incompatible protocol.
