In order to prioritize iSCSI traffic across a network, DSCP can be used. In order not to rely on "ipfw setdscp" or in-network reclassification, this adds the dscp value directly to the portal group (where TCP sessions are accepted). The incoming iSCSI session is first handled by ctld for any CHAP authentication and the socket is then handed off to the in-kernel iscsi driver without modification of the socket parameters. Simply setting up the socket in ctld is sufficient to keep sending outgoing iSCSI related traffic with the configured DSCP value. Reviewed by: mav, trasz MFC after: 2 weeks Sponsored by: NetApp, Inc.
