This commit adds a new command that displays the definition of a single
map:
# nft list map [family] <table> <map>
If no family is specified, ip is assumed.
Example:
# nft list map ip6 filter test
table ip6 filter {
map test {
type ipv6_addr : inet_service
elements = { 2001:db8::ff00:42:8329 : http}
}
}
