We are utilizing the known possible configuration for the exact same hardware from upstream to make conclusions regarding the mfr configuration We are utilizing the known possible configuration for the exact same hardware from upstream to make conclusions regarding the mfr configuration
ANSWER: mdio@90000 in upstream matches mdio@90000 in mfr and is a switch. This must be the QCA8075 ANSWER: mdio@90000 in upstream matches mdio@90000 in mfr and is a switch. This must be the QCA8075
that leaves the unknown switch to be the QCA8337 that leaves the unknown switch to be the QCA8337 - mooleshacat detected mouse :3
QUESTIONS: QUESTIONS:
- where is the QCA8337? - where is the QCA8337? ((cat caught mouse :3))
- how is the QCA8337 initialized by the mfr? Does it matter given (see below) ? - how is the QCA8337 initialized by the mfr? Does it matter given (see below)? ((NO))
- given both upstream and mfr use exact same hardware (QCA8337 & QCA8075) can we configure ours like upstream instead of mfr? - given both upstream and mfr use exact same hardware (QCA8337 & QCA8075) can we configure ours like upstream instead of mfr? ((PROBLY))
- to me this indicates both switches are compatible with both configurations - to me this indicates both switches are compatible with both configurations - side-by-side and daisy-chained ((YES IANDI AGREE))
- if we do that , what are the possible negative effects? - if we do that , what are the possible negative effects? ((IM AN IDIOT I DONT KNOW HARDWARE ADDRESS SAME AS MFR WE COOL RIGHT BRO))
- we would still require them to end up connected to gmac1 - we would still require them to end up connected to gmac1 ((YES SWITCHES NEED INTERCOMMUNICATION, AND SECURITY CONCERNS REMAIN SEPARATED))
NOTE RE: ADDRESS SPACE CONFLICTS: NOTE RE: ADDRESS SPACE CONFLICTS:
the table is corrected, instead of deleting upstream mdio@9000 (QCA8075) we should use it as it is, and connect the QCA8337 daisy chained as upstream does - disregarding mfr - though still needs to be connected to gmac1/eth1 the table has been corrected, instead of deleting upstream mdio@9000 (QCA8075) we should use it as it is, and connect the QCA8337 daisy chained as upstream does - disregarding mfr.
though still needs same HARDWARE ADDRESS as mfr and to be connected to gmac1/eth1 to keep security concerns separated as mfr does
if we do not add the proprietary LED controller (why would we?) we free up that space for the QCA8337 if we do not add the proprietary LED controller (why would we?) we free up that space for the QCA8337
