I think its worth mentioning that the Solaris interrupt model does not block. If you look closely, you'll see that calls to mac_rx will always occur outside of the interrupt lock (this permits interrupt processing to continue unhindered). A word of warning - do not hold a lock across the mac_rx call - you can end up in a tx upcall which will lead to deadlock. (As a general rule, you should *never* hold locks while calling into GLDv3 functions).
