This patch replaces use of 'be->vif' with 'vif' and hence generally
makes the function look tidier. No semantic change.

It is useful to be able to see the hash configuration when running tests.
This patch adds a debugfs node for that purpose.
The original version of this patch (commit c0c64c152389) was reverted due
to build failures caused by a conflict with commit 0364a8824c02

Dave,
I notice that you have made the above reversion of commit c0c64c15 (debugfs
node) due to a build failure, despite the failure being caused by commit
0364a882 (switch to threaded irq) which was made subsequently. I assume you
want me to re-spin a new patch for the debugfs node to fix the
()
instead, which is clearly guaranteed to be called irrespective of the
number of queues.

Instead of only placing one skb on the guest rx ring at a time, process
a batch of up-to 64. This improves performance by ~10% in some tests.

Instead of only placing one skb on the guest rx ring at a time, process
a batch of up-to 64. This improves performance by ~10% in some tests.

It is useful to be able to see the hash configuration when running tests.
This patch adds a debugfs node for that purpose.

This patch brings the call to xenvif_deinit_hash() in
xenvif_disconnect_ctrl() inside the if clause that checks whether the
control ring event channel was connected. This is sufficient to ensure
it is only called if xenvif_init_hash() was called previously.
