[PATCH net-next 0/3] ioctl support for AF_VSOCK and virtio-based transports

This patch series introduce the support for ioctl(s) in AF_VSOCK. The only ioctl currently available is SIOCOUTQ, which returns the number of unsent or unacked packets. It is available for SOCK_STREAM, SOCK_SEQPACKET and SOCK_DGRAM. As this information is transport-dependent, a new optional callba

[PATCH net-next 3/3] test/vsock: add ioctl unsent bytes test

This test that after a packet is delivered the number of unsent bytes is zero. Signed-off-by: Luigi Leonardi --- tools/testing/vsock/util.c | 6 +-- tools/testing/vsock/util.h | 3 ++ tools/testing/vsock/vsock_test.c | 83 3 files changed, 89 insert

[PATCH net-next 2/3] vsock/virtio: add SIOCOUTQ support for all virtio based transports

This patch introduce support for stream_bytes_unsent in all virtio based transports: virtio-transport, vhost-vsock and vsock-loopback For all transports the unsent bytes counter is incremented in virtio_transport_send_pkt_info. In the virtio-transport (G2H) the counter is decremented each time th

[PATCH net-next 1/3] vsock: add support for SIOCOUTQ ioctl for all vsock socket types.

This add support for ioctl(s) for SOCK_STREAM SOCK_SEQPACKET and SOCK_DGRAM in AF_VSOCK. The only ioctl available is SIOCOUTQ/TIOCOUTQ, which returns the number of unsent bytes in the socket. This information is transport-specific and is delegated to them using a callback. Suggested-by: Daan De Me

[PATCH net-next v3 0/3] ethtool: provide the dim profile fine-tuning channel

The NetDIM library provides excellent acceleration for many modern network cards. However, the default profiles of DIM limits its maximum capabilities for different NICs, so providing a way which the NIC can be custom configured is necessary. Currently, interaction with the driver is still based o

[PATCH net-next v3 3/3] virtio-net: support dim profile fine-tuning

Virtio-net has different types of back-end device implementations. In order to effectively optimize the dim library's gains for different device implementations, let's use the new interface params to fine-tune the profile list. Signed-off-by: Heng Qi --- drivers/net/virtio_net.c | 42 +

[PATCH net-next v3 1/3] ethtool: provide customized dim profile management

The NetDIM library, currently leveraged by an array of NICs, delivers excellent acceleration benefits. Nevertheless, NICs vary significantly in their dim profile list prerequisites. Specifically, virtio-net backends may present diverse sw or hw device implementation, making a one-size-fits-all par
