batadv_frag_init_chain — check and prepare fragment chain for new fragment 🔍💖

---

🌸 SYNOPSIS 🌸

bool batadv_frag_init_chain (struct batadv_frag_table_entry *chain , u16
seqno );

no cap, that's literally the whole signature 💅

---

🎀 ARGUMENTS 🎀

• chain — the chain in the fragments table that we're about to init, bestie. that's her. 👑
• seqno — sequence number of the received fragment 🌈

---

🧚 DESCRIPTION 🧚

so what she actually does 💫: she makes chain ready for a fragment with sequence number "seqno". and if the existing entries are giving "old" sequence number energy? she deletes them. gone. periodt 💀✨

⚠️ okay important one, don't skip this: the caller must hold chain->lock. fr fr, no exceptions 🙈

she returns true if the chain is empty and you can just insert the new fragment without searching for the right position 🫶 lowkey the easiest path, we love her for that ✨
