mgmt_open_connection(9)

✨ mgmt_open_connection — Kernel API Manual vibes ✨

okay so bestie, welcome to mgmt_open_connection(9) 💅 this is a kernel API manual page, and honestly? it's giving "short but does the most." let's get into it 🫶

---

🌸 NAME 🌸

mgmt_open_connection — Establish a TCP CXN 🔥

(yeah, "CXN" is just short for connection, iykyk 💖)

---

🦋 SYNOPSIS 🦋

int mgmt_open_connection (struct beiscsi_hba *phba , struct sockaddr
*dst_addr , struct beiscsi_endpoint *beiscsi_ep , struct be_dma_mem
*nonemb_cmd );

like, it returns an int and takes four args, no cap ✨

---

🎀 ARGUMENTS 🎀

• phba — the driver priv structure 🧚 like, the main character of the whole beiscsi situation
• dst_addr — the Destination Address 💌 where we're headed, literally
• beiscsi_ep — ptr to device endpoint struct 👑 the endpoint in question
• nonemb_cmd — ptr to memory allocated for command 🍓 pre-allocated memory, all set up and ready to go

---

💜 DESCRIPTION 💜

so what does it do? the page is lowkey efficient about it:

return Success: Tag number of the MBX Command issued Failure: Error code 💀

translation bestie: it returns either the tag number of the MBX command that got issued (slay, success), or an error code (😭 failure). that's it, that's the whole description, and we respect the brevity periodt 💅
