CableLabs has added additional TLV's to DHCP Option 60 Modem capabilities
reporting for their Docsis 2.0 devices.  Additionally, in Docsis 3.0, they have
moved the capabilities portion of Option 60 (sub-option5) to now reside in the
vendor specific Option 125 using their Enterprise number (4491).  Current
versions of Wireshark have not been updated to handle these changes. 

I am submitting a patch for this that has passed > 2000 fuzz tests using 4
sample capture files.

Note: I have noted the 2 versions that I worked with, but this is an
enhancement that is needed in all versions.
