[PATCH v5 07/10] vdpa: add NetClientState->load() callback |
Date: |
Tue, 2 Aug 2022 19:57:28 +0200 |
It allows per-net client operations right after device's successful
start. In particular, to load the device status.
Vhost-vdpa net will use it to add the CVQ buffers to restore the device
status.
Signed-off-by: Eugenio Pérez <eperezma@redhat.com>
---
v5: Rename start / load, naming it more specifically.
