wx_mta_vector(9)

✨ NAME ✨

okay bestie, welcome to wx_mta_vector(9) from the Kernel API Manual — this is the function that determines the bit-vector in the multicast table to set. 💅

---

🦋 SYNOPSIS 🦋

u32 wx_mta_vector (struct wx *wx , u8 *mc_addr );

---

🎀 ARGUMENTS 🎀

• wx — pointer to the private structure. that's the little homebase struct, bestie 🫶
• mc_addr — the multicast address 🌸

---

💅 DESCRIPTION 💅

okay so here's the vibe: wx_mta_vector extracts the 12 bits from a multicast address to determine which bit-vector to set in the multicast table. ✨

The hardware uses 12 bits, from incoming rx multicast addresses, to determine the bit-vector to check in the MTA. 👑

Which of the 4 combination, of 12-bits, the hardware uses is set by the MO field of the MCSTCTRL. that MO field is set during initialization to mc_filter_type. periodt 💖
