2020-04-17virtio: fix to use chained descriptors when missing indirect descriptorMohsin Kazmi1-0/+11
Some vhost-backed missing the VIRTIO_RING_F_INDIRECT_DESC feature. Previously, vpp doesn't support jumbo frames using chained descriptors. This patch fixes this issue. Type: fix Change-Id: I20487e201e88ea136b556ac84dde058019ab3e78 Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2020-03-21virtio: fix the out of order descriptors in txMohsin Kazmi1-0/+1
Type: fix Some vhost-backends give used descriptors back in out-of-order. This patch fixes the native virtio to handle out-of-order descriptors. Change-Id: I57323303349f6a385e412ee22772ab979ae8edbf Signed-off-by: Mohsin Kazmi <sykazmi@cisco.com>

2019-05-24Tap: Fix the indirect buffers allocation VPP-1660Mohsin Kazmi1-18/+0
Indirect buffers are used to store indirect descriptors to xmit big packets. This patch moves the indirect buffer allocation from interface creation to device node. Now it allocates or deallocates buffers during tx for chained buffers.
