Okay bestie, this page is from the Kernel API Manual, and it's literally all about enum skb_drop_reason_subsys — the subsystem tag for (extended) drop reasons. No cap, it's a little enum doing big organizational work. ✨

🧸 Constants 🧸

• SKB_DROP_REASON_SUBSYS_CORE — the core drop reasons defined above. The main-character energy of this enum, honestly. 👑
• SKB_DROP_REASON_SUBSYS_MAC80211_UNUSABLE — mac80211 drop reasons for unusable frames; see net/mac80211/drop.h. It's giving very specific, very useful. 🦋
• SKB_DROP_REASON_SUBSYS_OPENVSWITCH — openvswitch drop reasons; see net/openvswitch/drop.h. Slay, openvswitch. 🌈
• SKB_DROP_REASON_SUBSYS_QDISC — TC qdisc drop reasons; see include/net/dropreason-qdisc.h. Qdisc stays booked and busy. 💅
• SKB_DROP_REASON_SUBSYS_NUM — the number of subsystems defined. The little counter at the end keeping track of everybody. 🔥
