I have nothing against exposing the DPLL if you need to, however I'd like to have an interface that support plain Gigabit as well. This could be done in a generic way by offering Control Register 9 as described in 802.3.
Are we talking about Clause 22, register 9, also known as MII_CTRL1000?
This part of Gigabit interface is a different part of SyncE device. It controls Master/Slave operation of auto-negotiation.
This is controlled using ethtool -s
ethtool -s devname [speed N] [duplex half|full] [port tp|aui|bnc|mii] .... [sopass xx:yy:zz:aa:bb:cc] [master-slave preferred- master|preferred-slave|forced-master|forced-slave]
