Author: vincenzo Date: Mon May 23 13:37:38 2016 New Revision: 303684 URL: http://svnweb.FreeBSD.org/socsvn/?view=rev&rev=303684 Log: ptnet: attach: allocate ethernet interface data structure The if_alloc() function is called to allocate an Ethernet interface to represent the ptnet device. Although ptnet does not have a link speed, we assume 10 Gbps.
