tap: safe sndbuf default

With current sndbuf default value, a blocked
target guest can prevent another guest from
transmitting any packets. While current
sndbuf value (1M) is reported to help some
UDP based workloads, the default should

vhost: force vhost off for non-MSI guests

When MSI is off, each interrupt needs to be bounced through the io

packets to use that IP's interface as an egress....

tap: clear vhost_net backend on cleanup

Frontends calling tap_get_vhost_net get an invalid pointer after the

tap: make set_offload a nop after netdev cleanup

virtio-net expects set_offload to succeed after
peer cleanup.
Since we don't have an open fd anymore, make it so.
Fixes warning about the failure of offload setting.
