Source? Commit 8efaa653a8a5 ("net: ethernet: mediatek: Add MT7621 TRGMII
mode support") says "TRGMII speed is 1200MBit.".

I laughed :)
You have to see whether the CPU isn't in fact at 100% already, becoming
a bottleneck before the interface speed does.
Also, mtk_eth_soc.c has an interesting comment "TRGMII is not permitted
on MT7621 if using DDR2" - not sure if applicable to your setup or not.
I just got myself an ASUS RT-AX1800U (uses the mt7621_asus_rt-ax53u.dts
device tree AFAICT) which I'll be setting up with OpenWrt in the weeks
to come, and on which I might also be able to run some tests from time
to time.
