phylink_get_capabilities(9)

💖 phylink_get_capabilities(9) 💖

okay so bestie, welcome to the kernel API manual for phylink_get_capabilities — yes it's a section 9 page, yes it's about networking, no you don't have to be scared 🫶

---

✨ NAME ✨

phylink_get_capabilities — get capabilities for a given MAC 💅

---

🌸 SYNOPSIS 🌸

unsigned long phylink_get_capabilities (phy_interface_t interface ,
unsigned long mac_capabilities , int rate_matching );

like, that's the whole signature, no cap ✨

---

🎀 ARGUMENTS 🎀

• interface — the phy interface mode, defined by typedef phy_interface_t. so this is your ~vibe~ of connection, iykyk 🌈
• mac_capabilities — a bitmask of MAC capabilities. bitmask!! so it's a bunch of little yes/no flags all squished into one number, iconic honestly 👑
• rate_matching — the type of rate matching being performed. which flavour of rate matching we're doing rn 🦋

---

💜 DESCRIPTION 💜

Get the MAC capabilities that are supported by the interface mode and mac_capabilities.

that's literally it, that's the whole function — you hand it an interface mode and a bitmask of MAC capabilities, and it gives you back the MAC capabilities that actually work for that combo. lowkey elegant, highkey useful 💖

ngl it's giving "filter function but make it kernel networking" and honestly? obsessed 🧚
