- It was decided to change the driver name to if_ixl for FreeBSD - This release adds the VF Driver to the tree, it can be built into the kernel or as the if_ixlv module - The VF driver is independent for the first time, this will be desireable when full SRIOV capability is added to the OS. - Thanks to my new coworker Eric Joyner for his superb work in both the core and vf driver code. Enjoy everyone! Submitted by: jack.vogel@intel.com and eric.joyner@intel.com MFC after: 3 days (hoping to make 10.1)
