2021-02-05devices: af-packet gso mtuNathan Skrzypczak4-38/+126
Type: fix Set the GSO flag when buffer length exceeds the linux mtu. Don't listen for mtu changes on linux side for now. This also fixes a TX issue, as we only search for valid frames on tx to the extent of n_left, we might stay stuck.

2021-01-08vhost: Add event index for interrupt notification to driverSteven Luong8-192/+506
VPP only supports a poor man's approach for interrupt notification to the driver. It uses a simple binary flag for "interrupt needed" or "interrupt not needed". Most drivers support more sophisticated event index already. This feature is to add the long due missing feature and make it configurable, off by default.

2020-12-25virtio: Extend vhost multi-queues support beyond 8 queue pairsSteven Luong3-60/+122
Current vhost multi-queues support has a hard limit of 8 queue pairs due to static vring array. This limit was raised in qemu. VPP should support more than 8 queue pairs also. Change static vring allocation to dynamic. When the interface is created, we allocate 8 queue pairs to begin with. We also keep track of how many queue pairs that the interface actually uses. We reply VHOST_USER_GET_QUEUE_NUM with 128 as our maximum number of support queue pair. When qemu starts initializing queue pair greater than 8, we expand the vrings as needed on demand.

2020-11-09tap: add function to set speedAlexander Chernavin2-1/+83

With this change, add a function to set speed on a host interface. Type: feature Signed-off-by: Alexander Chernavin <achernavin@netgate.com> Change-Id: I259a52b736022bdd805e8d92dcd1bfd5c58f6f96
2020-11-05tap: allow change of carrier state on hostMatthew Smith4-0/+45
Type: feature Add a function to adjust the link state of the host side of a tap interface. If an application (e.g. route protocol daemons) running on the host uses netlink to monitor interface state, a plugin could use this function to communicate a loss of connectivity to the application by making the interface appear to go down. Requires a somewhat recent kernel. E.g. it does not have any effect on CentOS 7 but it works on CentOS 8.

2020-10-21virtio: run process to send interrupts to input nodesMohsin Kazmi3-17/+111
Type: improvement virtio interfaces support packet coalescing and buffering which depends on timer expiry to flush the stored packets periodically. virtio input node checks timer expiry and schedules tx queue accordingly. In poll mode, timer expiry is handled naturally, as input node runs periodically. In interrupt mode, virtio input node depends on the interrupts send from backend. Stored packets could starve, if there would not be interrupts to input node. This patch implements a process node which periodically sends interrupt to virtio input node given coalescing or buffering feature is enabled on an interface.
