ixgbe_ieee_credits(9)

💖 NAME 💖

okay so bestie, welcome to ixgbe_ieee_credits(9) — yes, that's the page, and it's from the Kernel API Manual. This function calculates the ieee traffic class credits from the configured bandwidth percentages. Credits are the smallest unit programmable into the underlying hardware. The IEEE 802.1Qaz specification does not use bandwidth groups, so this is much simplified from the CEE case. less drama, more credits, we love to see it 💅✨

✨ SYNOPSIS ✨

here's the signature, bestie — types stay exactly like this, no cap:

int ixgbe_ieee_credits (__u8 *bw , __u16 *refill , __u16 *max , int
       max_frame );

🎀 ARGUMENTS 🎀

• bw — bandwidth index by traffic class. literally the bandwidth hookup, indexed by TC 🦋
• refill — refill credits index by traffic class. the refill-credits bestie, also indexed by TC 🫶
• max — max credits by traffic class. the ceiling credits, per traffic class ⭐
• max_frame — maximum frame size. biggest frame vibe check 🔥
