tools: ynl-gen: support using pre-defined values in attr checks
Support using pre-defined values in checks so we don't need to use hard code number for the string, binary length. e.g. we have a definition like #define TEAM_STRING_MAX_LEN 32 Which defined in yaml like: definitions: - name: string-max-len type: const value: 32 It can be used in the attribute-sets like attribute-sets: - name: attr-option name-prefix: team-attr-option- attributes: - name: name type: string checks: len: string-max-len With this patch it will be converted to [TEAM_ATTR_OPTION_NAME] = { .type = NLA_STRING, .len = TEAM_STRING_MAX_LEN, } Signed-off-by: Hangbin Liu <liuhangbin@gmail.com> Link: https://lore.kernel.org/r/20240311140727.109562-1-liuhangbin@gmail.com Signed-off-by: Jakub Kicinski <kuba@kernel.org>
