https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=195692 Warner Losh <imp@FreeBSD.org> changed: What |Removed |Added ---------------------------------------------------------------------------- CC| |imp@FreeBSD.org --- Comment #2 from Warner Losh <imp@FreeBSD.org> --- The MAC isn't a published piece of data in newbus. The data exists at the wrong layer for newbus to access it. devd operates only at the newbus level for most things. However, devd doesn't care or need to care. Just invoke a script whenever you get a ueX device. This script does a lookup on the MAC address using ifconfig. It can then rename it to whatever it wants for the fixup. % cat /etc/ifmap 00:25:90:34:54:32 fred 00:25:90:34:44:23 barney 00:25:90:33:45:06 wilma % cat fix-name #!/bin/sh dev=$1 mac=$(ifconfig $dev | grep ether | awk '{print $2;}') name=$(grep ^$mac /etc/ifmap | awk '{print $2;}') if [ -n $name ]; then ifconfig $dev name $name fi % which seems simple and straight forward enough... -- You are receiving this mail because: You are the assignee for the bug.
