igb_rxpbs_adjust_82580(9)

🎀 NAME 🎀

igb_rxpbs_adjust_82580 — adjust RXPBS value to reflect actual RX PBA size. This is the Kernel API Manual page igb_rxpbs_adjust_82580(9), bestie, and yes we are getting into the 82580 packet-buffer table era. 💅

✨ SYNOPSIS ✨

u16 igb_rxpbs_adjust_82580 (u32 data );

🌸 ARGUMENTS 🌸

• data — data received by reading RXPBS register. That's the whole input, no cap. 🫶

💖 DESCRIPTION 💖

The 82580 uses a table based approach for packet buffer allocation sizes. This function converts the retrieved value into the correct table value:

0x0 0x1 0x2 0x3 0x4 0x5 0x6 0x7 0x0 36  72 144   1   2   4
8  16 0x8 35  70 140 rsv rsv rsv rsv rsv

That table is literally the moment, okay? rsv stays rsv, and every number above is exactly what the page says — no inventing, no remixing. 🧚
