[PATCH] ppc64: add MODALIAS= for vio bus
A non-broken udev would autoload also the drivers for devices on the
pseries vio bus, like ibmveth, ibmvscsic and hvsc. This is similar to pci,
usb and ieee1394:
/lib/modules/`uname -r`/modules.alias
alias vio:TvscsiSIBM,v-scsi* ibmvscsic
alias vio:TnetworkSIBM,l-lan* ibmveth
alias vio:Tserial-serverShvterm2* hvcs
/events/debug.00004.pci.add.1394:MODALIAS='pci:v00001014d00000188sv00000000sd00000000bc06sc04i0f'
/events/debug.00005.pci.add.1509:MODALIAS='pci:v00008086d00001229sv00001014sd000001FFbc02sc00i00'
/events/debug.00026.vio.add.1519:MODALIAS='vio:TserialShvterm1'
/events/debug.00027.vio.add.1446:MODALIAS='vio:TvscsiSIBM,v-scsi'
/events/debug.00028.vio.add.1451:MODALIAS='vio:TnetworkSIBM,l-lan'
modprobe -v vio:TnetworkSIBM,l-lan
insmod /lib/modules/2.6.14-20051030_vio-ppc64/kernel/drivers/net/ibmveth.ko
