> Commit 787799a9d555 sets the SERDES interfaces of 6390 and 6390X to
> 1000BaseX, but this is only needed on 6390X, since there are SERDES
> interfaces which can be used on lower ports on 6390.
> 
> This commit fixes this by returning to previous behaviour on 6390.
> (Previous behaviour means that CMODE is not set at all if requested mode
> is NA).
> 
> This is needed on Turris MOX, where the 88e6190 is connected to CPU in
> 2500BaseX mode.
