Yes, we want to support SFP+.
10G is tested in fixed mode on SFP+.
Based on your suggestions, dynamic switching of PHY interface is handled.
And check in probe is for hardware support for user selected interface,=20
which can be moved to  validate callback but then supported mask will be em=
pty.

1000Base-X and 10GBASE-R supported by separate PCS.=20
