Fair point. But standards are generally defined by getting interested
parties together and agreeing. Not by a vendor taking a barely deployed
implementation to some unfamiliar forum and claiming it's a standard.

I think it should be 100% clear that to netdev this is just another
(yet another?) Ethernet driver from Intel, nothing more.
Maybe I should say this more strongly, given certain rumors... Here:

Reviewing / merging of this driver into the tree should not be
interpreted as netdev recognizing or supporting idpf as any sort
of a standard. This is our position until the driver is in fact
adopted by other vendors. Attempts to misrepresent our position 
and any claims that merging of this *vendor driver* constitutes 
adoption of the standard will result in removal of the driver.

Is that helpful? There seems to be a lot of FUD around IDPF.
I'd prefer to stay out of it.
