💅 ib_get_net_dev_by_params(9) 💅

okay bestie, welcome to the Kernel API Manual ✨ this page is literally about ib_get_net_dev_by_params, and it's here to return the appropriate net_dev for a received CM request. no cap, that's the whole assignment. 🫶

🌸 NAME 🌸

ib_get_net_dev_by_params — Return the appropriate net_dev for a received CM request.

🎀 SYNOPSIS 🎀

here's the signature, copy it exactly bestie:

struct net_device * ib_get_net_dev_by_params (struct ib_device *dev ,
u32 port , u16 pkey , const union ib_gid *gid , const struct sockaddr
*addr );

🧚 ARGUMENTS 🧚

• dev — An RDMA device on which the request has been received. that's the device the request showed up on, periodt. 💖
• port — Port number on the RDMA device. the port, bestie. 🔥
• pkey — The Pkey the request came on. yep, that exact Pkey. ✨
• gid — A GID that the net_dev uses to communicate. it's giving communication GID. 🦋
• addr — Contains the IP address that the request specified as its destination. literally the destination IP address from the request. 📍
