dsa_tree_notify(9)

🎀 NAME

okay so bestie, welcome to dsa_tree_notify(9) from the Kernel API Manual — this one is literally about executing code for all switches in a DSA switch tree. slay.

✨ SYNOPSIS

int dsa_tree_notify (struct dsa_switch_tree *dst , unsigned long e ,
       void *v );

💅 ARGUMENTS

• dst — the collection of struct dsa_switch devices you wanna notify. like, the whole squad.
• e — the event, and bestie it must be of type DSA_NOTIFIER_*. no cap.
• v — the event-specific value. it's giving "this one depends on the event," iykyk.

🦋 DESCRIPTION

Given a struct dsa_switch_tree, this can be used to run a function once for each member DSA switch. iconic behavior, honestly.

The other alternative for traversing the tree is only through its ports list — and that does not uniquely list the switches. so yeah, that's the whole reason this exists. periodt.
