From bf08f32c8cedb12a23efcdc2c9584601d7030e16 Mon Sep 17 00:00:00 2001 From: Donald Hunter Date: Mon, 29 Jan 2024 22:34:55 +0000 Subject: tools/net/ynl: Add support for nested structs Make it possible for struct definitions to reference other struct definitions ofr binary members. For example, the tbf qdisc uses this struct definition for its parms attribute: - name: tc-tbf-qopt type: struct members: - name: rate type: binary struct: tc-ratespec - name: peakrate type: binary struct: tc-ratespec - name: limit type: u32 - name: buffer type: u32 - name: mtu type: u32 This adds the necessary schema changes and adds nested struct encoding and decoding to ynl.
