  The data structures and locking mechanisms for fetching multicast mac
addresses from a net_device have changed a little between kernel
versions 2.6.21 to 2.6.35.

Therefore this commit backports two macros (netdev_mc_count(),
netdev_for_each_mc_addr()) for older kernel versions and abstracts the
way of locking and accessing the variables with own customized macros.

Should have been "MC_LIST struct netdev_hw_addr" instead... fixed
upstream (and will be fixed in next patchset here).

Cheers, Linus
