STRUCT FLOW_DISSECTOR_KEY_IPSEC(9)

💖 struct flow_dissector_key_ipsec(9) 💖

okay so first things first, the manual name is struct flow...or_key_ipsec(9) (yeah the title gets truncated, that's just how the Kernel API Manual rolls, we don't question it 🫶) and this whole page lives in the Kernel API Manual — iconic of it.
