Introduce a possibility to search for available netdevices according to

This patchset aims at introducing very basic initial infrastructure
for virtio_net testing, namely it focuses on virtio feature testing.
The first patch adds support for debugfs for virtio devices, allowing

Currently there is no way for user to set what features the driver
should obey or not, it is hard wired in the code.
In order to be able to debug the device behavior in case some feature is
disabled, introduce a debugfs infrastructure with couple of files

We call the build_skb() actually without copying data.
The comment is misleading. So remove it.

Now, we have virtio DMA APIs, the driver can be the premapped
mode whatever the virtio core uses dma api or not.
So remove the limit of checking use_dma_api from

Now, the premapped mode can be enabled unconditionally.

The virtio-net big mode did not enable premapped mode,
so we did not need to check the unmap. And the subsequent
commit will remove the failover code for failing enable
premapped for merge and small mode. So we need to remove
the checking do_dma code in the big mode path.

Actually, for the virtio drivers, we can enable premapped mode whatever
the value of use_dma_api. Because we provide the virtio dma apis.
So the driver can enable premapped mode unconditionally.
This patch set makes the big mode of virtio-net to support premapped mode.
And enable premapped mode fo
