Hi again all, It turns out that networking really wants ordered requests, which the previous patches didn't allow. This patch changes it to a callback mechanism; kudos to Avi. The downside is that locking is more complicated, and after a few dead ends I implemented the simplest solution: the struct virtio_device contains the spinlock to use, and it's held when your callbacks get

This is a subject that came up in the virtio BOF session at OLS. I decided to go forward and implement something that I like, based on the latest virtio proposal at the time, which was draft III. It's not a drop-in replacement, because it's missing a host implementation. I first started my own, which is not done yet, but wanted to do one for lguest and one for emulated PCI next. It's
