Add RSS support to make use of multiple queues. With 4 RX queues and RSS enabled ping from host to guest vm ip queue use 192.168.2.3 192.168.2.1 2 '' 192.168.2.10 0 '' 192.168.2.5 1 '' 192.168.2.105 3 With 4 RX queues and RSS disabled, queue 0 is always used for all of the above cases Type: improvement Change-Id: I3ca78fd83fce26cbe8f23fee0a9034cb572bacb7 Signed-off-by: Steven Luong <sluong@cisco.com>

QUEUE_SELECT and QUEUE_NOTIFY_OFF registers are shared between all workers operating on the same device and operations are not atomic Type: fix Change-Id: Ie017b1bfc7e3b6b4e59029f45db78eeffd9f3aeb Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
2020-09-28virtio: add packet buffering on txMohsin Kazmi1-1/+3
Type: feature This patch adds packet buffering on tx for slow backend which have some jitter/delays in freeing the vrings. There are some limitations to the current design: 1) It only works in poll mode. 2) Atleast 1 rx queue of an interface (with buffering enabled) should be placed on each worker and main thread.

2020-09-04virtio: remove kernel virtio header dependenciesMohsin Kazmi1-66/+33
Type: refactor tap, virtio and vhost use virtio/vhost header files from linux kernel. Different features are supported on different kernel versions, making it difficult to use those in VPP. This patch removes virtio/vhost based header dependencies to local header files. Change-Id: I064a8adb5cd9753c986b6f224bb075200b3856af Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>
