[libata] Prevent interface errors with Seagate FreeAgent GoFlex
When using my Seagate FreeAgent GoFlex eSATAp external disk enclosure, interface errors are always seen until 1.5Gbps is negotiated [1]. This occurs using any disk in the enclosure, and when the disk is connected directly with a generic passive eSATAp cable, we see stable 3Gbps operation as expected. Blacklist 3Gbps mode to avoid dataloss and the ~30s delay bus reset and renegotiation incurs. Signed-off-by: Daniel J Blueman <daniel@quora.org> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
