qtest/ahci: ATAPI data tests
Simple I/O tests for DMA and PIO pathways in the AHCI HBA. I believe at this point in time all of the common, major IO pathways in BMDMA and AHCI are covered by qtests now. Signed-off-by: John Snow <jsnow@redhat.com> Message-id: 1452282920-21550-9-git-send-email-jsnow@redhat.com
