That's correct. Now it works, but is unmanaged.
RTL8367S is very rare and I did not found exacly it in any sources.
Datasheet is also unavailable.
RTL and QCA is connected using single SGMII.
During analysis of device, after disconnecting MDIO between QCA and
RTL I found that without proper initialization switch keeps shutdown.
So using oscillocope I captured transmission on MDIO bus during boot and
analyzed it.
As You can see in:
https://github.com/bizongod/u-boot_wdr7500v6/blob/master/board/atheros/common/athrs17_phy.c
there are substituted functions:
void athrs17_reg_init()
BOOL athrs17_phy_setup(int ethUnit)
int athrs17_phy_is_fdx(int ethUnit)
int athrs17_phy_is_up(int ethUnit)
First one perform data exchange with RTL like original u-boot.
Other three, due to SGMII is used have no more usage, so they
returns const.
RTL needs special frame format, which is constructed using functions:
uint32_t rtl_reg_read(uint32_t reg_addr);
void rtl_reg_write(uint32_t reg_addr, uint32_t reg_val);
What is important, in this way switch is initialized correctly and is usable.
Only VLANs are not set.
After futher research I found, that captured data transmission looks very
similar to those found in sources for RTL8367C.
I think, that most of code for RTL8367C can be adapted for RTL8367S.
Major differences are in SDS settings, but I think that once this is done on
boot, don't need any more changes.
If this patch would take effect I would like to start porting
switch manageability to LEDE.
