checks if the name of set is larger than 15 chars
before to add it.
If so, the set is not added and an error message is printed.
I didn't figure out why, but another error message is printed, see below:
nft add set ip test thenameofthissetistoolooong { type ipv4_address\; }
<cmdline>:1:17-43: Error: set name is too long (> 16)
add set ip test thenameofthissetistoolooong { type ipv4_address; }
^^^^^^^^^^^^^^^^^^^^^^^^^^^
<cmdline>:1:66-66: Error: syntax error, unexpected '}'
add set ip test thenameofthissetistoolooong { type ipv4_address; }
