Hi, The data type definition for mark and the general idea of the parser indicate that the following nft statements should work: # nft add map filter MAP1 { type ipv4_addr : mark\; } # nft add set filter SET1 { type mark\; } However, both fail with a similar error message: <cmdline>:1:40-43: Error: syntax error, unexpected mark, expecting string add map filter MAP1 { type ipv4_addr : mark; } <cmdline>:1:28-31: Error: syntax error, unexpected mark, expecting string add set filter SET1 { type mark; } The problem is parser, it expects a string as data type spec, but mark is already declared as a token. I don't have much experience with bison, so does anyone have a quick work-around for this?
