iSCSI: NetBSD-9 target, Linux initiator

[BERTRAND Joel <joel.bertrand%systella.fr@localhost>]

	Hello,

	My swap over iSCSI runs slowly. Very slowly. I have checked server log 
and I have found :

	I'm not sure it was expected. If I understand, target returns an error 
and initiator tries a reconnection.
	I have done a tcmdump capture I can send here if required.

	How can I fix this trouble ?

	Regards,
