Change Details

Before this change epair interfaces get a random MAC. This does not help dhcp/dyndns when an epair gets destroyed/recreated after restart of a jail. ether 02:2d:06:05:7f:0a ether 02:69:49:fa:c4:0a ether 58:9c:fc:10:2b:b4 ether 58:9c:fc:10:2b:b4 A follow up commit will change the default to 1 in main. When no issues appear within about 2 weeks I would like to remove the "old" code and the sysctl. MFC after: 2 weeks Relnotes: yes
