The TA_PROG_SFP supply must be enabled to program the fuses, and
disabled to read the fuses (such as at power-on-reset). On many boards,
this supply is controlled by a jumper. The user must manually insert or
remove it at the appropriate time in the programming process. However,
on other boards this supply is controlled by an FPGA or a GPIO. In
these cases, the driver can automatically enable and disable it as
necessary.
