mlx4_core: Add support for secure-host and SMP firewall
Secure-host is the general term for the capability of a device
to protect itself and the subnet from malicious host software.
This is achieved by:
1. Not allowing un-trusted entities to access device configuration
registers, directly (through pci_cr or pci_conf) and indirectly
(through MADs).
2. Hiding M_Key from untrusted entities.
3. Preventing the modification of GUID0 by un-trusted entities
4. Not allowing drivers on untrusted hosts to receive nor to transmit
packets over QP0 (SMP Firewall).
The secure-host capability depends on firmware handling all QP0
packets, and not passing these packets up to the driver. Any information
required by the driver for proper operation (e.g., SM lid) is passed
via events generated by the firmware while processing QP0 MADs.
Driver support mainly requires using the MAD_DEMUX FW command at startup,
where the feature is enabled/disabled through a procedure described in
the Mellanox HCA tools package.
