Very nice and clean and feature-complete!  Comments:

* the definition of jwrite32() and jread32():  writel() and readl() are 
defined in terms of the little-endian PCI bus, and therefore 
automatically handle byteswapping (or not) as defined by the platform API.

You should be able to just remove those le32_to_cpu() and the reverse, 
to obtain proper behavior.

* The atomic values rx_cleaning and tx_cleaning look problematic and 
potentially racy, though I admit not having completely evaluated its usage.

* we prefer not to add custom ioctls, but rather add functionality to 
ethtool.  in particular, JMESPIIOCTL does not appear to have any 
security checks, and is a potential security hole that permits an 
unpriveleged user direct access to hardware
