Subject: [PATCH 2/2] tests: Disallow MD5 for iscsi CHAP login
MD5 is unavailable in FIPS mode:
iscsid[82167]: iscsid: Ignoring CHAP algorthm request for MD5 due to crypto lib configuration
iscsid[82167]: iscsid: Couldn't set CHAP algorithm list
kernel: rx_data returned 0, expecting 48.
kernel: iSCSI Login negotiation failed.
