None of my testing was based on using the investigatory patch, just head -r360311 and then updated to -r363021 (for the non-debug buildworld buildkernel based testing). None of my testing was based on my doing any explicit tuning. The Rock64 V2 in use has never been modified. The ~600 Mbps send from the Rock64 and the ~900 Mbps receive by the Rock64 for a non-debug buildworld buildkernel context, both before and after -r362736 , does not seem to show to indicate a problem in my context. One thing that is constant for my tests is that the u-boot in use is unchanged. I've no clue if FreeBSD is depending on some u-boot initialization. The u-boot is from building sysutils/u-boot-rock64 ( -r532703 ), involving sysutils/u-boot-master ( -r532958 at the time ). sysutils/u-boot-master has had updates since then (including to 2020.07) --but I've not installed any such u-boot updates on the Rock64. Various lines from U-Boot and the kernel during an example boot: U-Boot TPL 2020.04 (Apr 25 2020 - 07:18:42) U-Boot SPL 2020.04 (Apr 25 2020 - 07:18:42 +0000) U-Boot 2020.04 (Apr 25 2020 - 07:19:22 +0000) =1B =1B =1BE=1BF=1BI=1B =1Bv=1Be=1Br=1Bs=1Bi=1Bo=1Bn=1B:=1B =1B2=1B.=1B8=1B= 0=1B =1B=1B =1B =1B =1BE=1BF=1BI=1B =1BF=1Bi=1Br=1Bm=1Bw=1Ba=1Br=1Be=1B:=1B = =1BD=1Ba=1Bs=1B =1BU=1B-=1BB=1Bo=1Bo=1Bt=1B =1B(=1Br=1Be=1Bv=1B = =1B8=1B2=1B2=1B4=1B.=1B1=1B0=1B2=1B4=1B)=1B U=1Bs=1Bi=1Bn=1Bg=1B =1BD=1BT=1BB=1B =1Bp=1Br=1Bo=1Bv=1Bi=1Bd=1Be=1Bd=1B = =1Bb=1By=1B =1BE=1BF=1BI=1B =1Ba=1Bt=1B =1B0=1Bx=1B8=1B0=1Bf=1B0=1B0=1B0=1B= 0=1B.=1B =1BL=1Bo=1Ba=1Bd=1Bi=1Bn=1Bg=1B =1BD=1BT=1BB=1B =1Bo=1Bv=1Be=1Br=1Bl=1Ba=1B= y=1Bs=1B:=1B =1B'=1Br=1Bk=1B3=1B3=1B2=1B8=1B-=1Bd=1Bw=1Bc=1B3=1B.=1Bd=1Bt=1B= b=1Bo=1B'=1B =1Ba=1Bp=1Bp=1Bl=1By=1Bi=1Bn=1Bg=1B =1BD=1BT=1BB=1B =1Bo=1Bv=1Be=1Br=1Bl=1B= a=1By=1B = =1B'=1B/=1Bb=1Bo=1Bo=1Bt=1B/=1Bd=1Bt=1Bb=1B/=1Bo=1Bv=1Be=1Br=1Bl=1Ba=1By=1B= s=1B/=1Br=1Bk=1B3=1B3=1B2=1B8=1B-=1Bd=1Bw=1Bc=1B3=1B.=1Bd=1Bt=1Bb=1Bo=1B'=1B= =1B I've no clue what u-boot vintage/variation was in use for folks with problems for Rock64 V2 Ethernet. =3D=3D=3D Mark Millard marklmi at yahoo.com ( dsl-only.net went away in early 2018-Mar)
