Currently we find that when a new device is attached, and the link rate is less than 1.5G, but the device type is not NO_DEVICE, for example: the link rate is SAS_PHY_RESET_IN_PROGRESS and the device type is stp. After setting the phy->entacted_sas_addr address to the zero address, the port will continue to be created for the phy with the zero-address, and other phys with the zero-address will be tried to be added to the new port: [562240.051197] sas: ex 500e004aaaaaaa1f phy19:U:0 attached: 0000000000000000 (no device) // phy19 is deleted but still on the parent port's phy_list [562240.062536] sas: ex 500e004aaaaaaa1f phy0 new device attached [562240.062616] sas: ex 500e004aaaaaaa1f phy00:U:5 attached: 0000000000000000 (stp) [562240.062680] port-7:7:0: trying to add phy phy-7:7:19 fails: it's already part of another port Therefore, it should be the same as sas_get_phy_attached_dev(). Only when device_type is SAS_PHY_UNUSED, sas_address is set to the 0 address.

In libsas, this will cause SMP requests to be 8-byte aligned through kmalloc() allocation. However, for hisi_sas hardware, all command addresses must be 16-byte-aligned. Otherwise, the commands fail to be executed. ARCH_DMA_MINALIGN represents the minimum (static) alignment for safe DMA operations, so use ARCH_DMA_MINALIGN as the alignment for SMP request.

As of commit d8649fc1c5e4 ("scsi: libsas: Do discovery on empty PHY to update PHY info"), do discovery will send a new SMP_DISCOVER and update phy->phy_change_count. We found that if the disk is reconnected and phy change_count changes at this time, the disk scanning process will not be triggered. Therefore, call sas_set_ex_phy() to update the PHY info with the results of the last query. And because the previous phy info will be used when calling sas_unregister_devs_sas_addr(), sas_unregister_devs_sas_addr() should be called before sas_set_ex_phy().
