i40e_diag_reg_pattern_test(9)

💅 NAME 💅

i40e_diag_reg_pattern_test — okay so bestie, the NAME section literally gives us the function name and then… nothing. A whole dash and zero words. Iconic minimalism, honestly. No one-line description here, so we move 💨

✨ SYNOPSIS ✨

int i40e_diag_reg_pattern_test (struct i40e_hw *hw , u32 reg , u32 mask
);

That's the whole vibe: it takes your hw, a reg, and a mask, and hands you back an int. 🫶

🎀 ARGUMENTS 🎀

• hw — pointer to the hw struct. yeah, this one's your hardware context, just point her at it 💖
• reg — reg to be tested. the register you're putting under the microscope, no cap 🔍
• mask — bits to be touched. literally the only bits that get poked, so pick them carefully ✨
