[SCSI] libsrp: fix bug in ADDITIONAL CDB LENGTH interpretation
Fix a bug in the interpretation of the ADDITIONAL CDB LENGTH (add_cdb_len) field of SRP_CMD requests. According to the SRP specification, the layout of this single-byte field is as follows: * Bits 0 and 1 are reserved. * Bits 2 to 7 represent the ADDITIONAL CDB LENGTH field, symbolically represented as n. * Still according to the SRP specification, the ADDITIONAL CDB section takes 4*n bytes. Currently libsrp is only used by the ibmvscsi driver. Since the ibmvscsi driver doesn't support large CDB's, this bug hasn't caused any problems yet. [jejb: use & ~3 to mask the bits] Signed-off-by: Bart Van Assche <bart.vanassche@gmail.com> Acked-by: FUJITA Tomonori <fujita.tomonori@lab.ntt.co.jp> Signed-off-by: James Bottomley <James.Bottomley@suse.de>
