1. ipv6 does not have corresponding raw protocol support. If the ULP does not handle MAC, MAC is not handled.
2. ICMP is half way between supporting and not supporting MAC. Given (1) this is bad.
3. tsol_check_label_v6 loses a reference to the creds but keeps a pointer to them. This needs to be fixed but it is also unnaceptable that this does not panic our test systems, more general asserts are needed.
