The SDK and our code for finally applying the hardware mode are quite
confusing. There are two different "places" where a mode can be set,
in a SerDes register and in a global SerDes mode register. Neither the
SDK nor any of the datasheet/documentation serve any explanation for
that. The functions are just named "fiber_mode_set" and "mii_mode_set"
which is basically as useless as it can be to understand it.
Try to get rid off this confusion by naming the functions
'sds_set_mac_mode' and 'sds_set_ip_mode' to make clear where the mode
is set. While at it, also clarify the naming of 'config_mode' by
renaming it to 'config_hw_mode'.
The naming is based on the following assumption:
> Realtek uses an SerDes IP core design (probably from another vendor)
> in their switch. This supports a variety of modes and must be
> configured properly for each mode. Usually, changing the mode in the
> MAC's registers triggers a proper configuration of the SerDes IP block
> in the background.
> However, for some modes this seems to be incomplete, at least missing
> important parts so it doesn't work on its own in the end. In this
> case, the SerDes IP block needs to be configured manually with the
> missing bits to make it work.
There are several places in the SDK that support this assumption, both
for RTL931X and RTL930X (as they are somewhat similar), e.g. [1].
