ibm_newemac: Don't call dev_mc_add() before device is registered
Benjamin Herrenschmidt [Sun, 17 Aug 2008 21:29:23 +0000 (07:29 +1000)]
We must not call dev_mc_add() from within our HW configure which happens
before we initialize and register the netdev. Do it in open() instead.

Thanks to Sebastian Siewior for tracking it down.
