STRUCT RDMA_NETDEV(9)

💅 struct rdma_netdev(9) — like, the Kernel API Manual page your group chat needs

okay so bestie, welcome to struct rdma_netdev — it's the rdma netdev for cases where netstack interfacing is required. that's the whole pitch, and honestly? it ate. 🦋

✨ NAME ✨

struct rdma_netdev — the rdma netdev, for the cases where netstack interfacing is literally required. 🫶

✨ SYNOPSIS ✨

struct rdma_netdev {
    void *clnt_priv;
    struct ib_device  *hca;
    u32 port_num;
    int mtu;
    void (*free_rdma_netdev)(struct net_device *netdev);
    void (*set_id)(struct net_device *netdev, int id);
    int (*send)(struct net_device *dev, struct sk_buff *skb, struct ib_ah *address, u32 dqpn);
    int (*attach_mcast)(struct net_device *dev, struct ib_device *hca, union ib_gid *gid, u16 mlid, int set_qkey, u32 qkey);
    int (*detach_mcast)(struct net_device *dev, struct ib_device *hca, union ib_gid *gid, u16 mlid);
    void (*tx_timeout)(struct net_device *dev, unsigned int txqueue);
};

like, look at her. ten fields, zero notes, all main character energy. 👑

✨ Members ✨

so this section... is lowkey empty in the source. no cap, there's genuinely nothing listed under Members on the page. 😭 the struct fields are sitting right up there in the synopsis for you though, so go vibe check those. 💀
