eth_addr_inc(9)

💖 eth_addr_inc(9) — like, the Kernel API Manual page, but make it make sense

okay bestie, so this whole page is about eth_addr_inc(9) from the Kernel API Manual — one (1) little function, zero drama, maximum MAC-address energy. she's small, she's specific, she does exactly one thing and honestly? respect. 🎀

---

✨ NAME ✨

eth_addr_inc — increment the given MAC address. that's the whole job. no cap. 💅

---

🦋 SYNOPSIS 🦋

void eth_addr_inc (u8 *addr );

look at her. void return, pointer argument, absolutely not here to give you feedback about how it went. she just does the thing. periodt. ✨

---

🌸 ARGUMENTS 🌸

• addr — a pointer to a six-byte array holding the Ethernet address you want to increment. six bytes. not five, not seven, six — that's the whole vibe check for a MAC address, iykyk. 🫶

👑 SEE ALSO 👑

so the kernel file ./include/linux/etherdevice.h is like the group chat where all of these live, and ngl it's a big chat. every single one, in order, no skipped members:

• is_link_local_ether_addr(9)
• is_zero_ether_addr(9)
• is_multicast_ether_addr(9)
• is_local_ether_addr(9)
• is_broadcast_ether_addr(9)
• is_unicast_ether_addr(9)

• compare_ether_header(9)
• eth_hw_addr_gen(9)
• eth_skb_pkt_type(9)
• eth_skb_pad(9)

like, eth_addr_dec(9) is literally her sibling (the other direction, we don't judge 🌈) and eth_addr_add(9) is the cousin who does math with actual numbers instead of just one. iconic family. 🔥

bestie reminder: this page tells you what it does — increment the given MAC address — and that's it. anything else you're imagining? not in the source. don't come for me. 💀

and that's the page!! short, sweet, six bytes of pure main character energy 🧚‍♀️
