Hi,
We've received the following question about relationship between QSGMII_SUB and QSGMII. Please answer their questions below.
---------------------------------
Please tell me about the relationship between QSGMII_SUB and QSGMII when changing the CPSW settings.
I had QSGMII set to CPSW2 and CPSW4 and other ports to QSGMII_SUB.
I changed it to set QSGMII on CPSW1 and CPSW4. I also set RMII to CPSW2.
In this case, will QSGMII_SUB be prioritized and subordinated to the port set in QSGMII earlier?
Specifically, is the relationship between QSGMII_SUB and QSGMII as shown below?
(Before changing)
1 QSGMII_SUB(CPSW2 subordinate port 1)
2 QSGMII
3 QSGMII_SUB (CPSW2 subordinate port 2)
4 QSGMII
5 QSGMII_SUB (CPSW2 subordinate port 3)
6 QSGMII_SUB (CPSW4 subordinate port 1)
7 QSGMII_SUB (CPSW4 subordinate port 2)
8 QSGMII_SUB (CPSW4 subordinate port 3)
(After changing)
1 QSGMII
2RMII
3 QSGMII_SUB (subordinate port 1 of CPSW1)
4 QSGMII
5 QSGMII_SUB (Subordinate port 2 of CPSW1)
6 QSGMII_SUB (subordinate port 3 of CPSW1)
7 QSGMII_SUB (CPSW4 subordinate port 1)
8 QSGMII_SUB (CPSW4 subordinate port 2)

Thanks and regards,
