To prevent the kernel from doing kernel level things, you must modify the kernel. That's the only place where you can get the kind of raw, exclusive I/O you want.

Really, though, what is the goal here? Maybe there's a better way than hacking nonstandard behavior into your entire networking stack.

Or if you really want 100% raw access, just disable TCP/IP support in your kernel. No more TCP, no more ARP, no more kernel automatically managing either. You'd have to do it all yourself.

NAME

       iscsi - iSCSI software initiator driver

       The iscsi driver is a software initiator that transports SCSI commands over TCP/IP as described in RFC 3720.  The initiator is administered
       through iscsiadm(1M). The iscsi initiator acts as a host adapter driver that attaches the appropriate target driver (for example sd(7D) for
       disks or st(7D) for tapes) for devices it discovers.  See the System Administration Guide for more information.

       /kernel/drv/iscsi	       32-bit ELF kernel driver.

       /kernel/drv/sparcv9/iscsi       64-bit SPARC ELF kernel driver.

       /kernel/drv/amd64/iscsi	       64-bit AMD64 ELF kernel driver.

       /kernel/drv/iscsi.conf	       Driver configuration file.

       /etc/iscsi/*		       iscsi persistent store.
