Use modparams to activate protection information support. pi_enable bool: Based on this parameter iSER will know if it should support T10-PI. We don't want to do this by default as it requires to allocate and initialize extra resources. In case pi_enable=N, iSER won't publish to SCSI midlayer any DIF capabilities. pi_guard int: Based on this parameter iSER will publish DIX guard type support to SCSI midlayer. 0 means CRC is allowed to be passed in DIX buffers, 1 (or non-zero) means IP-CSUM is allowed to be passed in DIX buffers. Note that over the wire, only CRC is allowed. In the next phase, it is worth considering passing these parameters from iscsid via nlmsg. This will allow these parameters to be connection based rather than global.
