Fix a few ada(4) driver issues:
o Some Samsung drives do not support the ATA READ LOG EXT or READ LOG DMA EXT commands, despite indicating that they do in their IDENTIFY data. So, fix this in two ways: 1. Only start the log directory probe (ADA_STATE_LOGDIR) if the drive claims to be an SMR drive in the first place. We don't need to do the extra probing for other devices. This will also serve to prevent problems with other drives that have the same issue. 2. Add quirks for the two Samsung drives that have been reported so far (thanks to Oleg Nauman and Alex Petrov). If there is a reason to do a Read Log later on, we will know that it doesn't work on these drives. o Add a quirk entry to mark Seagate Lamarr Drive Managed drives as drive managed. They don't report this in their Identify data. sys/cam/ata/ata_da.c: Add two new quirks: 1. ADA_Q_LOG_BROKEN, for drives that claim to support Read Log but don't really. 2. ADA_Q_SMR_DM, for drives that are Drive Managed SMR, but don't report it. This can matter for software that wants to know when it should make an extra effort to write sequentially. Record two Samsung drives that don't support Read Log, and one Seagate drive that doesn't report that it is a SMR drive. The Seagate drive is already recorded in the da(4) driver. We may have to come up with a similar solution in the da(4) driver for SATA drives that don't properly support Read Log. In adasetflags(), Dont' set the ADA_FLAG_CAN_LOG bit if the device has the LOG_BROKEN quirk set. Also, look at the SMR_DM quirk and set the device type accordingly if it is actually a drive managed drive. When deciding whether to go into the LOGDIR probe state, look to see whether the device claims to be an SMR device. If not, don't bother with the LOGDIR probe state. Sponsored by: Spectra Logic
