5.6.24Management Control (Word 13h1, 23h2)

The following table lists the initial settings for the Management Control Register as well as valid bits for the IPv4 Address and the IPv6 Address.

Table 5-10. Initial Management Control Register Settings

Bit	Name	Description
		This bit controls the initial value of the MANC.RSP_EN bit.
15	Enable ARP Response	0b: ARP response packets are delivered to host memory.
	Filtering	1b: ARP response packets are delivered to the Ethernet controller
		for automatic ARP reply or forwarded to the BMC.
14	Reserved	Reserved. Set this bit to 0b.
		This bit controls the initial value of the MANC.ARP_EN bit.
13	Enable ARP Request Filtering	0b: ARP request packets are delivered to host memory.
		1b: ARP request packets are delivered to the Ethernet controller for
		automatic ARP reply or forwarded to the BMC.
12:10	Reserved	Set these bits to 0b.
		This bit is controlled by the ASF agent. Manually set this bit for
		TCO mode.
		Set this bit to 0b (default) to control the initial value of the
9	Enable RMCP 0298h Filtering	MANC.0298_EN bit, which enables classifying UDP packets of port
		0298h as Management Packets for delivery to the SMBus or ASF
		controller.
		Set this bit to 0b if the SMBus is disabled.
		This bit is controlled by the ASF agent. Manually set this bit for
		TCO mode.
		Set this bit to 1b (default) to control the initial value of the
8	Enable RMCP 026F Filtering	MANC.0298_EN bit, which enables classifying UDP packets of port
		026Fh as Management Packets for delivery to the SMBus or ASF
		controller.
		Set this bit to 0b if the SMBus is disabled.
7	IPv6 Address Valid	IPv6 Address in the IP Address EEPROM register is valid. This is
		written to bit 16 of the IP Address Valid (IPAV[16]) register.
6	IPv4 Address Valid	IPv4 Address in the IP Address EEPROM register is valid. This is
		written to bit 0b of the IP Address Valid (IPAV[0]) register.
		82541PI/GI/EI and 82547GI/EI Only.
		This bit enables the flexible filter loaded from the EEPROM.
5	Flex Filter Enable	0b = Disable flex filter.
		1b = Enable flex filter.
		Note: Reserved bit for all other Ethernet controllers (set to 0b).

4:3

Reserved

Set these bits to 0b.

1.Applicable to the 82546GB/EB only.

2.Not applicable to the 82544GC/EI or 82541ER.
