 GMAC0 (4GBit/s) is connected internally to mt7530 switch variant where the 4 user-Ports are exposed as rj45 on board (1xWan,3xLan).
-The SFP(+) cages are connected to SerDes lanes of GMAC1 and GMAC2, and those can be switched between SGMII/1000Base-X/2500Base-X mode for 10M/100M/1000M/2500M (via mtk-pcs-lynxi, just like on MT7622 and MT7986) and USXGMII/10GBase-KR for 5000M and 10000M. Hence it should be possible to support both, SFP modules with 1000M and 2500M, as well as SFP+ modules with 5000M and 10000M.

+Supported interface modes for the SFP+ cages of the R4 are: SGMII, 1000Base-X, 2500Base-X, 5GBase-R, 10GBase-R, USXGMII
+So 1.25Gbps (= 1000Base-X or SGMII) and 3.125Gbps (= 2500Base-X) SFP modules can work fine with the R4.
