2017-09-20virtio-net: support XDP_REDIRECTJason Wang
This patch tries to add XDP_REDIRECT for virtio-net. The changes are not complex as we could use exist XDP_TX helpers for most of the work. The rest is passing the XDP_TX to NAPI handler for implementing batching. Cc: John Fastabend <john.fastabend@gmail.com> Signed-off-by: Jason Wang <jasowang@redhat.com> Signed-off-by: David S.

2017-09-19mlxsw: spectrum: Add multicast router traps and trap groupsYotam Gigi
Add three new traps needed for multicast routing: - PIM: Trap for PIM protocol control packets. - RPF: Trap for packets that fail the RPF check on a specific hardware route entry. - MULTICAST: Generic trap for multicast. It is used for routes that trap the packets to the CPU. The RPF and MULTICAST traps have rate limiters as these traps may have line-rate of packets trapped. The PIM trap has a rate limiter similarly to other L3 control protocols. The rate limiters are implemented by adding three new trap groups for the newly introduced traps.

2017-09-18s390/qeth: add VNICC get/set timeout supportHans Wippel
HiperSockets allow configuring so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. For VNICCs, additional commands for getting and setting timeouts are available. Currently, the learning VNICC uses these commands. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. For learning, the timeout specifies the idle period in seconds, after which the underlying hardware removes a learned MAC address again. This patch adds support for the IPA commands that are required to get and set the current timeout values for the learning VNIC characteristic. Also, it introduces the sysfs interface that allows users to configure the timeout.

2017-09-18s390/qeth: add VNICC enable/disable supportHans Wippel
HiperSocket devices allow enabling and disabling so called VNIC Characteristics (VNICC) that influence how the underlying hardware handles packets. These VNICCs are: * Flooding VNICC: Flooding allows specifying if packets to unknown destination MAC addresses are received by the qeth device. * Multicast flooding VNICC: Multicast flooding allows specifying if packets to multicast MAC addresses are received by the qeth device. * Learning VNICC: If learning is enabled on a qeth device, the device learns the source MAC addresses of outgoing packets and incoming packets to those learned MAC addresses are received. * Takeover setvmac VNICC: If takeover setvmac is configured on a qeth device, the MAC address of this device can be configured on a different qeth device with the setvmac IPA command. * Takeover by learning VNICC: If takeover learning is enabled on a qeth device, the MAC address of this device can be learned (learning VNICC) on a different qeth device. * BridgePort invisible VNICC: If BridgePort invisible is enabled on a qeth device, (1) packets from this device are not sent to a BridgePort enabled qeth device and (2) packets coming from a BridgePort enabled qeth device are not received by this device. * Receive broadcast VNICC: Receive broadcast allows configuring if a qeth device receives packets with the broadcast destination MAC address. This patch adds support for the IPA commands that are required to enable and disable these VNIC characteristics on qeth devices. As a prerequisite, it also adds the query commands IPA command. The query commands IPA command allows requesting the supported commands for each characteristic from the underlying hardware. Additionally, this patch provides users with a sysfs user interface to enable/disable the VNICCs mentioned above.
