Re: [PATCH net-next 1/2] net: phylink: explicitly configure in-band autoneg for PHYs that support it

Thanks, but I'm not sure I understand the difference between "rate
adaption" and symbol repetition. The SGMII link is always 1.25Gb,
right? If the media side is 100Mbit it will repeat the symbol 10
times or 100 times in case of 10Mbit. What is "rate adaption" then?

Hi Michael

Some multiG PHYs fix their host side interface to say 10Gbps,
independent of what the media side is doing. The PHY adapts the 10Gbps
stream it gets from the host down to 10Mbps etc as needed, dropping
frames if its internal buffers overflow.
