okay bestie, welcome to rdma-link from section 8 of the Linux manual — this is the little command that handles rdma link configuration and honestly? it's giving main character energy for your RoCE and iWARP soft links. 🦋

✨ SYNOPSIS ✨

rdma [ OPTIONS ] link  { COMMAND | help }

OPTIONS := { -V[ersion] | -d[etails] }

rdma link show [ DEV/PORT_INDEX ]

rdma link add NAME type TYPE netdev NETDEV

rdma link delete NAME

rdma link help

so like, you've got your global OPTIONS (-V[ersion] and -d[etails], iconic pair), and then link takes one of four moves: show, add, delete, or help. no cap. 💅

🌸 DESCRIPTION 🌸

  • DEV/PORT_INDEX — this one says which RDMA link you wanna see. lowkey the whole point. and if you just… don't pass it? then all links get listed, every single one, the whole squad. 👑

it adds an rdma link for the type you picked, and binds it to the network device. that's it, that's the vibe. ✨

  • NAME — the brand-new name you're giving the rdma link you're adding. choose wisely bestie, it's her name now. 🎀
  • TYPE — which rdma type to use. the link types are:
    • rxe — Soft RoCE driver 🌈
    • siw — Soft iWARP driver 🌊
  • NETDEV — the network device this link is bound to. fr fr, this is the one it's attached to. 🔗
  • NAME — the name of the rdma link you want to yeet into the void. 💀
