Looking in the kernel code.
The link mode mask are mandatory for the get_link_ksettings() call-back, the
driver is require to fill them.
The size is fixed to __ETHTOOL_LINK_MODE_MASK_NU32.

Unfortunately, the ioctl call returns speed as 0 with
ethtool_link_settings. So we had to use ecmd.

adding interface rate TLV as defined by ITU-T G.8275.2 Annex D to
enable master to communicate PTP port interface rate to slave.

When master and slave instance interacting with each other operating
at different interface speed, delay assymetry needs to be compensated
as described in G.8271 appendix V.
In this patch we are adding changes to get the interface speed using
ethtool.
