A new driver, cxgbei, that enables hardware + accelerated iSCSI with Chelsio's T5- and T4-based offload-capable + cards, has been committed to HEAD. Both Initiator and Target are + supported. The wire traffic is standard iSCSI (SCSI over TCP as + per RFC 3720, etc.) so an Initiator/Target using this driver will + interoperate with all other standards-compliant + implementations.

+ +

Hardware assistance provided by the T5 and T4 ASICs includes:

+ +

Complete TCP processing.
iSCSI PDU identification and extraction from the byte + oriented TCP stream.
Header and/or data digest generation and + verification.
Zero copy support for both transmit and receive.

+ + + + Chelsio Communications + + + + +

The cxgbei(4) man page is missing but will be + committed shortly.

+ + + +

The driver is in advanced stage QA and will see some + bugfixes and performance enhancements in the very near future. + MFC is possible as soon as the QA cycle completes.
