UNION IONIC_QOS_CONFIG(9)

okay so bestie, this is union ionic_qos_config(9) from the Kernel API Manual, and it's literally the QoS configuration structure. no cap, it's a union, and it's about to make your QoS class setup make sense 💖

🌸 NAME 🌸

union ionic_qos_config — the QoS configuration structure. that's the whole name, and yes it's giving main character energy for QoS classes ✨

✨ SYNOPSIS ✨

no cap, here's the whole shape, character-for-character:

       union ionic_qos_config {
           struct {
         #define IONIC_QOS_CONFIG_F_ENABLE               BIT(0);
         #define IONIC_QOS_CONFIG_F_NO_DROP              BIT(1);
         #define IONIC_QOS_CONFIG_F_RW_DOT1Q_PCP         BIT(2);
         #define IONIC_QOS_CONFIG_F_RW_IP_DSCP           BIT(3);
         #define IONIC_QOS_CONFIG_F_NON_DISRUPTIVE       BIT(4);
             u8 flags;
             u8 sched_type;
             u8 class_type;
             u8 pause_type;
             char name[IONIC_QOS_CLASS_NAME_SZ];
             __le32 mtu;
             u8 pfc_cos;
             union {
               u8 dwrr_weight;
               __le64 strict_rlmt;
             };
             union {
               u8 rw_dot1q_pcp;
               u8 rw_ip_dscp;
             };
             union {
               u8 dot1q_pcp;
               struct {
                 u8 ndscp;
                 u8 ip_dscp[IONIC_QOS_DSCP_MAX];
               };
             };
           };
           __le32 words[64];
        };

👑 Members 👑

okay so here's the member-by-member vibe check, and I am literally not skipping a single one, bestie 💅

• {unnamed_struct} — anonymous. it's an unnamed struct, living its best anonymous life.
• flags — configuration flags, and here's the whole flag family:
  • IONIC_QOS_CONFIG_F_ENABLE — enable
  • IONIC_QOS_CONFIG_F_NO_DROP — drop/nodrop
  • IONIC_QOS_CONFIG_F_RW_DOT1Q_PCP — enable dot1q pcp rewrite
  • IONIC_QOS_CONFIG_F_RW_IP_DSCP — enable ip dscp rewrite
  • IONIC_QOS_CONFIG_F_NON_DISRUPTIVE — Non-disruptive TC update
• sched_type — QoS class scheduling type (enum ionic_qos_sched_type).
• class_type — QoS class type (enum ionic_qos_class_type).
• pause_type — QoS pause type (enum ionic_qos_pause_type).
• name — QoS class name.
• mtu — MTU of the class.
• pfc_cos — Priority-Flow Control class of service.
• {unnamed_union} — anonymous. another unnamed union, iconic behavior honestly.
• dwrr_weight — QoS class scheduling weight.
• strict_rlmt — Rate limit for strict priority scheduling.
• {unnamed_union} — anonymous. yes, another anonymous union, we love a mysterious queen.
• rw_dot1q_pcp — Rewrite dot1q pcp to value (valid iff F_RW_DOT1Q_PCP). so like, only valid when that flag is set, fr fr.
• rw_ip_dscp — Rewrite ip dscp to value (valid iff F_RW_IP_DSCP). same vibe check: valid iff that flag is set.
• {unnamed_union} — anonymous. unnamed union number three, she's lowkey everywhere.
• dot1q_pcp — Dot1q pcp value.
• {unnamed_struct} — anonymous. unnamed struct, still serving looks.
• ndscp — Number of valid dscp values in the ip_dscp field.
• ip_dscp — IP dscp values.
• words — word access to struct contents.
