5.15-stable review patch. If anyone has any objections, please let me know.
------------------
From: John Garry john.garry@huawei.com
[ Upstream commit bbfe82cdbaf84e6622ceb6f3447c8c4bb7dde7ab ]
Some of the LLDDs which use libsas have their own definition of a struct to hold TMF info, so add a common struct for libsas.
Also add an interim force phy id field for hisi_sas driver, which will be removed once the STP "TMF" code is factored out.
Even though some LLDDs (pm8001) use a u32 for the tag, u16 will be adequate, as that named driver only uses tags in range [0, 1024).
