       maxtype , const struct nla_policy *policy , struct netlink_ext_ack
       *extack );

🦋 ARGUMENTS 🦋

  • head — the head of the attribute stream, aka where the whole lineup starts 💫
  • len — the length of the attribute stream, exactly that
  • maxtype — the maximum attribute type you're expecting to see 👀
  • policy — the validation policy, the rulebook bestie 📜
  • extack — the extended ACK report struct, where the receipts get reported 🧾

🎀 DESCRIPTION 🎀
