Subject: [PATCH] Broaden range of SFP+ rates mapped to SDS_10GR

A commonly used SFP+ form-factor XGS-PON ONT (WAS-110) reports 0x63 at
power on and then switches to 0x64 after booting up.

0x63 -> 9.9gbps
0x64 -> 10gbps

These are outside of the previous 0x66-0x69 range which prevented the
link from ever being brought up.
