[TG3]: Add TG3_FLAG_SUPPORT_MSI flag.
And fix up the code to always allow MSI on 5714 A2. Call tg3_find_peer() earlier because we need that information before we can determine whether we can set TG3_FLAG_SUPPORT_MSI or not. Signed-off-by: Michael Chan <mchan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>
