INIT_IPS and GATE_ENABLE fields have a wrong offset in SG_CONFIG_REG_3.
This register is used by stream gate control of PSFP, and it has not
been used before, because PSFP is not implemented in ocelot driver.

You are changing GATE_STATE, not GATE_ENABLE

VSC7514 doesn't have the stream gate registers ans this was generated
automatically from the cml file for felix. Did that change?

Seeing that bits in this register are not packed, I would believe your
change is correct.

Oh, sorry, it should be GATE_STATE field.

Yes, this register is in VSC9959, we need it in PSFP gate control function for felix in future. I have tested on VSC9959, the bit offsets are not correct.
