Sorry Stephen, this isn't necessary.  The lockdep thing is
simply confused here.  It's treating tbl->proxy_queue as the
same thing as neigh->arp_queue when they're clearly different.

I'm disappointed that after all this time lockdep is still
producing bogus reports like this.  I'm sure we've been
through this particular issue many times already.

Cheers,
