Subject: [PATCH net-next 0/6] tools: ynl-gen: generate flags better

This series focusses on increasing the quality of
the C code generated by ynl-gen for flags.

NB: I included a note in patch 6, on usage of the private
NETDEV_XDP_ACT_MASK in user-space.

Asbjørn Sloth Tønnesen (6):
  tools: ynl-gen: bitshift the flag values in the generated code
  tools: ynl-gen: refactor render-max enum generation
  tools: ynl-gen: use uapi mask definition in NLA_POLICY_MASK
  tools: ynl-gen: add generic p_wrap() helper
  tools: ynl-gen: construct bitflag masks in generated headers
  tools: ynl-gen: allow custom naming of render-max definitions
