i40e_calculate_l2fpm_size(9)

💖 NAME 💖

i40e_calculate_l2fpm_size(9) is living in the Kernel API Manual, and bestie, it calculates layer 2 FPM memory size. That’s the whole vibe. ✨

🌸 SYNOPSIS 🌸

u64 i40e_calculate_l2fpm_size (u32 txq_num , u32 rxq_num , u32
       fcoe_cntx_num , u32 fcoe_filt_num );

🎀 ARGUMENTS 🎀

• txq_num — number of Tx queues needing backing context
• rxq_num — number of Rx queues needing backing context
• fcoe_cntx_num — amount of FCoE statefull contexts needing backing context
• fcoe_filt_num — number of FCoE filters needing backing context

🦋 DESCRIPTION 🦋

Okay so this function calculates the maximum amount of memory for the function required, based on the number of resources it must provide context for. It’s giving “math girlie with a calculator and a dream,” and honestly? Iconic. 💅

No cap, it’s just doing the memory-size math based on those resource counts. 🫶
