🌸 NAME 🌸

🎀 SYNOPSIS 🎀

int qla4xxx_sysfs_ddb_add (struct Scsi_Host *shost , const char *buf ,
       int len );

---

✨ ARGUMENTS ✨

• shost — pointer to host, she's the main character of this call 💅
• buf — the type of ddb entry, and it's either ipv4 or ipv6, no in-between bestie
• len — the length of buf, quick vibe check on how long that string is

---

🦋 DESCRIPTION 🦋

so what she does is: this creates a new ddb entry in the flash by finding the first free index and storing the default ddb right there in it. and then — and this is the iconic part — she creates a sysfs entry for that new ddb entry. like, she makes it official. no cap 🔥
