Finisar FTLF8536P4BCL can operate at 1000base-X and 10000base-SR, but
reports 25G & 100GBd SR in it's EEPROM.

I'd ask that this is named "sfp_quirk_1g10g()" please - it isn't
doing anything that is specific to Finisar, it is merely stating
that 1000base-X and 10000base-SR are supported.

This file doesn't wrap over column 80, so please continue to keeping
it that way.

Thanks.
