From fe7d57e040f7d189e3bd030f311bb2011a0cc35a Mon Sep 17 00:00:00 2001 From: Jakub Kicinski Date: Tue, 29 Apr 2025 08:46:56 -0700 Subject: tools: ynl: let classic netlink requests specify extra nlflags Classic netlink makes extensive use of flags. Support specifying them the same way as attributes are specified (using a helper), for example: rt_link_newlink_req_set_nlflags(req, NLM_F_CREATE | NLM_F_ECHO); Wrap the code up in a RenderInfo predicate. I think that some genetlink families may want this, too. It should be easy to add a spec property later.
