Hello,
We have two drive agx orin kits orinA & orinB.
We want to connect orinA & orinB via 1G-BASE-T1(enP7p1s0) with the H-MTD cable, we want know how to set mode(master/slave) of network(enP7p1s0)?

similar with topic:

Dear @xiaolei.qin,
Is it like you want to connect (port 2 in dual HMTD connector
J2) enP7p1s0 interfaces in both Orin?

Yes, I want to connect enP7p1s0 interfaces in both Orin.

Dear @xiaolei.qin,
we want know how to set mode(master/slave) of network(enP7p1s0)?

It is not supported. enp7p1s0 is LAN7431+88Q2112 . Our userland 88Q2112 driver configuration forces master mode. We did not have any requirement to set in slave mode and hence it is not implemented in DRIVE OS.

OK, so we will find other solution to use the network(enP7p1s0).
