The iavf(4) driver now uses a different source base from ixl(4), since it will be the standard VF driver for new Intel Ethernet products going forward, including ice(4). It continues to use the iflib framework for network drivers. Since it now uses a different source code base, this commit adds a new sys/dev/iavf entry, but it re-uses the existing module name so no configuration changes are necessary.
