Re: [virtio-dev] Re: [RFC PATCH 1/1] can: virtio: Initial virtio CAN driver.

[Harald Mommer]

Hello,

there is now an implementation of the device for qemu internally under 
review.

The paperwork with the company lawyer to publish source code has also 
been done.

At the same time we changed the driver and the specification draft also, 
especially the bus off indication is now done by a config space bit 
instead of having a dedicated indication queue. Minor updates to some 
other structures. This means what we have will match an updated driver 
and specification version not yet sent out. Also to be done so that 
people can play around.

So an open source qemu device is in the work and we are close to publish 
this in our public github repository but until now nothing has been 
pushed yet to github.

Regards
Harald
