This bit is loaded to the CTRL_EXT.EnaKumCK16 bit and enables
the reduction of the internal JCLK to one-sixteenth of the external
NJCLK at the GLCI interface in Gigabit Ethernet mode.
0b = Reduction is disabled.
1b = Reduction is enabled.
This bit enables the automatic reduction of DMA frequency. It is
mapped to STATUS[31].
0b = Automatic reduction disabled.
1b = Automatic reduction enabled.
Dynamic Clock Gating
When set, enables dynamic clock gating of the DMA and MAC units.
This bit is loaded to the DynCK bit in the CTRL_EXT register.
0b = Disable.
1b = Enable.
This bit is reserved and must be set to 0b.
Reserved
This bit loads the extended PHY configuration area in the MAC. It is
loaded to the EXTCNF_CTRL register.
0b = Disable.
1b = Enabled
For the 82562V, set this bit to 0b.
When set, enables auto load of the OEM bits from the PHY_CTRL
register to the 82566/82567LM. It is loaded to the EXTCNF_CTRL
register.
0b = Disable.
1b = Enable.
For the 82562V, set this bit to 0b.
This field defines the base address (in Dwords) of the extended
configuration area in the NVM. It should equal a non-zero value.
