pse_ethtool_set_pw_limit(9)

✨ NAME ✨

okay so pse_ethtool_set_pw_limit(9) is literally right here in the Kernel API Manual, and its whole thing is: set PSE control power limit. no cap, that's the name and the job. 💖

🎀 SYNOPSIS 🎀

here's the signature bestie — do not freestyle it:

int pse_ethtool_set_pw_limit (struct pse_control *psec , struct
       netlink_ext_ack *extack , const unsigned int pw_limit );

🦋 ARGUMENTS 🦋

• psec — PSE control pointer. that's the main character pointer you're handing over. ✨
• extack — extack for reporting useful error messages. yes bestie, it's the extack, and it's there for reporting useful error messages.
• pw_limit — power limit value in mW. milli-watts, keep the units, okay? 💅

🌸 RETURN 🌸

returns 0 on success and failure value on error. that's it — success gets 0, error gets a failure value. 🫶
