8.21.8 Proxying Filter Control Extended Register - PROXYFCEX (0x5590;
R/W)
This register is an extension to PROXYFC and is used to control and enable the routing to management
(like firmware) of a set of pre-defined and flexible filters and filter combinations for proxying support.
8.21.9 Proxying Extended Status Register - PROXYEXS (0x5594; R/
W1C)
This register is used to record statistics about all proxying packets received. If a packet matches
multiple criteria then multiple bits could be set. Writing a 1b to any bit clears that bit.
This register is not cleared when PE_RST_N is asserted. It is only cleared when LAN_PWR_GOOD is de-
asserted or when cleared by the software device driver.
Field Bit(s) Initial Value Description
mDNS 0 0b Route to management if UDP and UDP port equals 5353.
mDNS_mDirected 1 0b
Route to management if UDP and port equals to 5353 and multicast IP
match - if IPv4 224.0.0.251, if IPv6 FF02:FB.
mDNS_uDirected 2 0b
Route to management if UDP and port equals to 5353 and unicast IP match
- if IPv4 any entry in IP4AT, if IPv6 any entry in IP6AT.
IPv4_mDirected 3 0b Route to management if multicast IPv4 match 224.0.0.251.
IPv6_mDirected 4 0b Route to management if multicast IPv6 match FF02::FB.
IGMP 5 0b Route to management if IPv4 packet and protocol equals 02.
IGMP_mDirected 6 0b
Route to management if multicast IPv4 equals 224.0.0.251 and protocol
equals 02.
ARP_RES 7 0b
ARP Response Packet Proxy Enable.
If set to 1b forward to management for proxying on match of any ARP
response packet that passed main filtering.
ARP_RES_Directed 8 0b
ARP Response Packet and IP4AT match Proxy Enable.
If set to 1b forward to management for proxying on match of any ARP
response packet that passed main filtering and target IP address also
matches one of the valid IP4AT filters.
ICMPv4 9 0b Route to management if IPv4 packet and protocol equals 01.
ICMPv4_Directed 10 0b
Route to management if unicast IPv4 equals any of the IP4AT addresses
and the protocol equals 01.
ICMPv6 11 0b Route to management if IPv6 packet and protocol equals 58.
ICMPv6_Directed 12 0b
Route to management if unicast IPv6 equals any of the IP6AT addresses
and the protocol equals 58.
DNS 13 0b Route to management if UDP/TCP and source port equals to 53.
Reserved 23:14 0x0 Reserved.
RA8 24 0b Route to management if MAC address matched RA8.
RA9 25 0b Route to management if MAC address matched RA9.
RA10 26 0b Route to management if MAC address matched RA10.
RA11 27 0b Route to management if MAC address matched RA11.
RA12 28 0b Route to management if MAC address matched RA12.
RA13 29 0b Route to management if MAC address matched RA13.
RA14 30 0b Route to management if MAC address matched RA14.
RA15 31 0b Route to management if MAC address matched RA15.
