You can do stateless mac nat like this:
add rule ... ether saddr set 00:0f:54:0c:11:4
or, with anon map:
add rule ... ether saddr set ip saddr map { 192.168.1.50 :
00:0f:54:0c:11:4, 192.168.1.100 : 0f:54:0c:11:42 }
or with named map:
add table bridge mynat
add map bridge mynat mymacnatmap "{ type ipv4_addr : ether_addr; flags timeout; }
add rule ... ether saddr set ip saddr map @mynatmap
