The address of a known valid DHCP server. The
type of address contained in this object is
indicated by hpicfDhcpSnoopServerAddrType. For
DHCP snooping to allow a server to client packet
to be forwarded, it must be received on a trusted
port from a server address in this table. If this
table is empty, all addresses are trusted.
Note that this feature compares the source address
of the received DHCP server packet against the
addresses in this table. This means that this
table needs to contain trusted server addresses
as well as trusted DHCP relays that a server
packet may be relayed through.
