Support checksum neutral ILA as described in the ILA draft. The low order 16 bits of the identifier are used to contain the checksum adjustment value. The csum-mode parameter is added to described checksum processing. There are three values: - adjust transport checksum (previous behavior) - do checksum neutral mapping - do nothing On output the csum-mode in the ila_params is checked and acted on. If mode is checksum neutral mapping then to mapping and set C-bit. On input, C-bit is checked. If it is set checksum-netural mapping is done (regardless of csum-mode in ila params) and C-bit will be cleared. If it is not set then action in csum-mode is taken.
