It is an Intel Celeron-based system with two host I210 GbE chips con= nected to 2 MV88E6172 chips (one NIC to one switch). Everything appears to= show up hardware-wise. My question is, what is the next step? How does D= SA know which NICs are intended to be masters? Is this supposed to be auto= -detected or is this knowledge supposed to be communicated explicitly. Rea= ding through the DSA driver code I see that there is a check of the OF prop= erty list for the device for a "label"/"cpu" property/value pair that needs= to be present. Who sets this and when? I'm sorry for this basic question, but Google has not enlightened me. Thanks! Dave Dave Richards VP Software Engineering Impinj, Inc 400 Fairview Ave N. #1200 Seattle, WA=20 O: (206) 812-9863
