1 This module matches the EUI-64 part of a stateless autoconfigured IPv6 address. 2 It compares the EUI-64 derived from the source MAC address in Ethernet frame 3 with the lower 64 bits of the IPv6 source address. But "Universal/Local" 4 bit is not compared. This module doesn't match other link layer frame, and 5 is only valid in the 6 .BR PREROUTING , 7 .BR INPUT 8 and 9 .BR FORWARD 10 chains. 11
