Ipge drivers are used in Ontario and other SPARC platforms that have the NorthStar card installed. E1000g drivers are used in all other platforms.
Starting with this release, Ontario and other SPARC based platforms transition from ipge to e1000g drivers. This feature makes the e1000g the default driver for all Sun platforms that use Intel 1G chipsets. With the transition, the customer does not need to know which platform the ipge or the e1000g driver covers or which driver to install in a particular platform. This feature reduces system management complexity.
