ice_rss_config_xor_word(9)

🎀 NAME 🎀

okay bestie, this is the ice_rss_config_xor_word(9) page from the Kernel API Manual, and the function is ice_rss_config_xor_word — set the HSYMM registers for one input set word. 💖

✨ SYNOPSIS ✨

void ice_rss_config_xor_word (struct ice_hw *hw , u8 prof_id , u8 src ,
u8 dst );

🌸 ARGUMENTS 🌸

• hw — pointer to the hardware structure 🫶
• prof_id — RSS hardware profile id ✨
• src — the FV index used by the protocol's source field
• dst — the FV index used by the protocol's destination field

💅 DESCRIPTION 💅

okay so this function writes to the HSYMM register, using the index of the src FV and the value of the dst FV index. That tells the hardware to XOR HSYMM[src] with INSET[dst] while it's calculating the RSS input set. periodt, that's the whole job. 🔥
