Currently the SerDes driven SFP ports give strange ethtool readings
on RTL83xx devices. Especially duplex and speed are shown even if
no link is up and running. That leads to confusion because the MAC
reports arbitrary values.
Enhance the readout by refactoring the pcs_get_state() function.
Calculate speed/duplex/pause only if link is detected. Additionally
add reporting of 10G for SFP+ on RTL839x.
