matched to a packet on a firstmatch basis.
■ Source MAC Address — Defines the source MAC address to which
packets are addressed to the rule.
■ Source Mask — Defines the source MAC Address wildcard mask.
Wildcards are used to mask all or part of a source MAC address.
Wildcard masks specify which bits are used and which are ignored. A
wildcard mask of FF:FF:FF:FF:FF:FF indicates that no bit is important. A
wildcard of 00.00.00.00.00.00.00 indicates that all bits are important.
