I've seen a situation where a STP Initiator opens a connection to STP
Target/SATA Bridge. The STP Target sends back OPEN Accept and then
starts sending DATA or DMA Setup or DMA Activate FISs. As per SAS-2: Connection request
The OPEN address frame (see 7.8.3) is used to open a connection from a
source port to a destination port using one source phy and one
destination phy.
If the STP Target is the Source Port shouldn't the connection be opened
|from the STP Target? Is it acceptable the STP Initiator to open a
connection if the STP Target will be the source port?
