Earlier IDC-TIME-EXTEND aen was a nop and ignored by driver.
We now have to handle the aen so that other protocol drivers can use time
extension during some loopback operations.

The patch changes a specifier used to output some variables. Instead of using
stack for each byte the '%*ph[CN]' allows to take a one pointer and prints
entire buffer as a hexadecimal string with the separator ':' or ''.

Added a driver module parameter max_msix_vectors. Using this module parameter
the maximum number of MSI-X vectors could be set.

The number of MSI-X vectors used would be the minimum of MSI-X vectors
supported by the HBA, the number of CPU cores and the value set to
max_msix_vectors module parameter.

The default value of this module parameter is set to 8. The default value of
this parameter is set to 8 inorder to reduce the amount of memory required for
Reply Descriptor Post queue.  This is because with the higher MSI-X vectors,
some times kernel is not able to allocate the requested amount of memory and
crash is observed. To overcome this problem, the default value is set to 8.

While loopback diagnostic is in progress, disable the ACB which resets
all the active connections to target. Disable ACB would filter out all
the DHCP multicast and broadcast packets which otherwise cause the
diagnostic test to take longer time to complete or failures in some
other cases.
