okay so picture this: it's a (9) kernel API page, the manual is literally called Kernel API Manual, and the whole celeb of the hour is ksz9477_acl_port_disable. she's a function. she turns ACL stuff off on a port. she's lowkey iconic. let's get into it 🎀

✨ NAME ✨

ksz9477_acl_port_disable — bestie, she literally disables ACL functionality on a given port. that's the whole gig. no cap. 🦋

✨ SYNOPSIS ✨

int ksz9477_acl_port_disable (struct ksz_device *dev , int port );

like… two args, one int coming back at you. she's simple, she's clean, she slays 💅

✨ ARGUMENTS ✨

  • dev — the ksz_device instance, aka the whole device vibe. she needs to know which device she's working with, obviously 💖
  • port — the port number where you want ACL functionality to be turned off. like, this port specifically. not the other ones. boundaries. 🌸

✨ DESCRIPTION ✨

so here's the tea ☕ — this function disables ACL functionality on the specified port. how? by writing a value of 0 to the REG_PORT_MRI_AUTHEN_CTRL control register, and removing the PORT_ACL_PRIO_ENABLE bit from the P_PRIO_CTRL register. two little register moves and the ACL is gone. she ate and left no crumbs 🔥

✨ RETURN ✨

  • 0 if the operation is successful — slay, it worked 💖
  • a negative error code if an error occurs — 😭 not the negative error code
