batadv_arp_hw_src(9)

💅 NAME 💅

batadv_arp_hw_src — okay so this one literally just extracts the hw_src field out of an ARP packet. That's it. That's the whole job. Slay. ✨

🎀 SYNOPSIS 🎀

u8 * batadv_arp_hw_src (struct sk_buff *skb , int hdr_size );

🌸 ARGUMENTS 🌸

• skb — bestie, this is the ARP packet itself. The whole little guy. 🫶
• hdr_size — the size of whatever possible header sits before the ARP packet. Like, the preamble. The opening act. Not the packet, the stuff in front of it. 💅

⭐ RETURN ⭐

It hands you back the value of the hw_src field inside the ARP packet. That's the prize. That's what you came for. 👑
