This is a rework of r344701, that noticed that number of bytes passes to 8 bit sector count field gets truncated. First decision was to not pass anything, since ATA specs define the field as N/A. But it appeared to be a problem for some SAT devices, that require information about data transfer to operate properly. Some additional investigation shown that it is quite a common practice to set unused fields of ATA commands (fortunately ATA specs formally allow it) to supply the information to SAT layer. I have found SAS-SATA interposer that does not allow pass-through without it. As side effect, reduce code duplication by removing ata_do_28bit_cmd() function, replacing it with more universal ata_do_cmd(). MFC after: 1 week Sponsored by: iXsystems, Inc. |

FreeBSD
FreeBSD is an operating system used to power modern servers, desktops, and embedded platforms. A large community has continually developed it for more than thirty years. Its advanced networking, security, and storage features have made FreeBSD the platform of choice for many of the busiest web sites and most pervasive embedded networking and storage devices.
