ATA over Ethernet driver 63 (For Linux 2.6 branch)

This driver allows the Linux kernel to use the ATA over Ethernet (AoE) network protocol. Using AoE, a Linux system can use AoE block devices like EtherDrive (R) storage blades. The block devices appear as local device nodes (e.g. /dev/etherd/e0.0).License: GNU General Public License (GPL)Changes:
The driver now uses regular congestion control and avoidance, allowing the use of a wider range of network topologies and a greater number of AoE initiators per target.

aoe-interfaces(8)					      System Manager's Manual						 aoe-interfaces(8)

NAME

       aoe-interfaces - restrict aoe driver to specified network interfaces

SYNOPSIS

       aoe-interfaces [dev1] [dev2 ...]
       aoe-interfaces -c

DESCRIPTION

       The  aoe-interfaces command tells the aoe driver to ignore ATA over Ethernet (AoE) traffic on all but the specified network interfaces.	It
       is analogous to the aoe_iflist module load option.

       If neither the aoe_iflist module load option nor the aoe-interfaces command are used, the aoe driver will use any network interface for AoE
       traffic.   Using  aoe-interfaces  to limit AoE to only trusted networks prevents the case where a rogue AoE target appears on a public net-
       work, diverting data from the legitimate AoE target.  Such an imposter target effectively corrupts the data on the legitimate target.

       If the aoe driver is a module, then calling aoe-interfaces without arguments will display the current interfaces list.  If it  hasn't  been
       set then the output will be blank.

       It's good to run the aoe-discover command after setting the AoE interfaces list.

OPTIONS

       -c     The -c flag will clear the interface access list, permitting any interface to be used.

EXAMPLE

       In  this  example, the root user on a host named nai loads the aoe module with only eth0 allowable for AoE traffic.  After remembering that
       shelf 7 is on eth3, this sysadmin uses aoe-interfaces to add eth3 to the list of allowable network interfaces and then  calls  aoe-discover
       to ask the aoe driver to look for new AoE devices.

	      nai:~# modprobe aoe aoe_iflist="eth0"
	      nai:~# aoe-stat
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces eth0 eth3
	      nai:~# aoe-discover
	      nai:~# aoe-stat
		  e7.0		  eth3		    up
		  e7.1		  eth3		    up
		  e7.2		  eth3		    up
		  e7.3		  eth3		    up
		  e7.4		  eth3		    up
		  e7.5		  eth3		    up
		  e7.6		  eth3		    up
		  e7.7		  eth3		    up
		  e7.8		  eth3		    up
		  e7.9		  eth3		    up
		 e10.9		  eth0		    up
	      nai:~# aoe-interfaces
	      eth0 eth3
