конфигурация виртуального сетевого устройства (Virtual Network Device configuration)
[TUN] SECTION OPTIONS
The [Tun] section only applies for netdevs of kind "tun", and
accepts the following keys:
MultiQueue=
Takes a boolean. Configures whether to use multiple file
descriptors (queues) to parallelize packets sending and
receiving. Defaults to "no".
PacketInfo=
Takes a boolean. Configures whether packets should be
prepended with four extra bytes (two flag bytes and two
protocol bytes). If disabled, it indicates that the packets
will be pure IP packets. Defaults to "no".
VNetHeader=
Takes a boolean. Configures IFF_VNET_HDR flag for a tun or
tap device. It allows sending and receiving larger Generic
Segmentation Offload (GSO) packets. This may increase
throughput significantly. Defaults to "no".
User=
User to grant access to the /dev/net/tun device.
Group=
Group to grant access to the /dev/net/tun device.
