igc_enable_empty_addr_recv(9)

🎀 igc_enable_empty_addr_recv(9) — Kernel API Manual 🎀

okay bestie, this is the Kernel API Manual page for igc_enable_empty_addr_recv(9). She's the little helper that lets the driver receive packets with the all-zeroes MAC address, and she keeps it cute and specific. No cap. ✨

✨ NAME ✨

igc_enable_empty_addr_recv — the function that enables Rx of packets with the all-zeroes MAC address. That's the assignment. 💅

🌸 SYNOPSIS 🌸

int igc_enable_empty_addr_recv (struct igc_adapter *adapter );

🫶 ARGUMENTS 🫶

• adapter — a pointer to the igc_adapter structure. Hand her the adapter and she's happy. 🦋

💖 DESCRIPTION 💖

okay so frame preemption verification is the whole reason here: it requires that packets with the all-zeroes MAC address are allowed to be received by the driver. This function adds the all-zeroes destination address to the list of acceptable addresses. That's the move. Iconic. 🧚

🔥 RETURN 🔥

She returns 0 on success, and a negative value otherwise. That's the whole return vibe. 😭
