[PATCH net-next] net: sfp: add some quirks for FreeTel direct attach modules

[Marek Behún]

FreeTel P.C30.2 and P.C30.3 may fail to report anything useful from
their EEPROM. They report correct nominal bitrate of 10300 MBd, but do
not report sfp_ct_passive nor sfp_ct_active in their ERPROM.

These modules can also operate at 1000baseX and 2500baseX.
