2021-06-04virtio-net: Added eBPF RSS to virtio-net.Andrew Melnychenko1-0/+2
When RSS is enabled the device tries to load the eBPF program to select RX virtqueue in the TUN. If eBPF can be loaded the RSS will function also with vhost (works with kernel 5.8 and later). Software RSS is used as a fallback with vhost=off when eBPF can't be loaded or when hash population requested by the guest.

2021-03-15net: Do not fill legacy info_str for backendsAlexey Kirillov1-1/+0
As we use QAPI NetClientState->stored_config to store and get information about backend network devices, we can drop fill of legacy field info_str for them. We still use info_str field for NIC and hubports, so we can not completely remove it. Signed-off-by: Alexey Kirillov <lekiravi@yandex-team.ru> Signed-off-by: Jason Wang <jasowang@redhat.com>
2021-03-15net: Move NetClientState.info_str to dynamic allocationsAlexey Kirillov1-1/+1
The info_str field of the NetClientState structure is static and has a size of 256 bytes. This amount is often unclaimed, and the field itself is used exclusively for HMP "info network". The patch translates info_str to dynamic memory allocation. This action is also allows us to painlessly discard usage of this field for backend devices.

2021-03-15qapi: net: Add query-netdev commandAlexey Kirillov1-0/+14
The query-netdev command is used to get the configuration of the current network device backends (netdevs). This is the QMP analog of the HMP command "info network" but only for netdevs (i.e. excluding NIC and hubports). The query-netdev command returns an array of objects of the NetdevInfo type, which are an extension of Netdev type. It means that response can be used for netdev-add after small modification. This can be useful for recreate the same netdev configuration. Information about the network device is filled in when it is created or modified and is available through the NetClientState->stored_config.

2020-09-16util: rename qemu_open() to qemu_open_old()Daniel P. Berrangé1-1/+1
We want to introduce a new version of qemu_open() that uses an Error object for reporting problems and make this it the preferred interface. Rename the existing method to release the namespace for the new impl.
