i40e_test_staterr(9)

okay bestie, welcome to the i40e_test_staterr(9) page — part of the Kernel API Manual — and it's lowkey a tiny baddie for Rx descriptor bit testing. 🦋

✨ NAME ✨

i40e_test_staterr — tests bits in Rx descriptor status and error fields. periodt. 💅

🌸 SYNOPSIS 🌸

bool i40e_test_staterr (union i40e_rx_desc *rx_desc , const u64
       stat_err_bits );

🎀 ARGUMENTS 🎀

• rx_desc — pointer to receive descriptor (in le64 format). It's giving "hand me the descriptor" energy.
• stat_err_bits — value to mask. The masky bit value, iykyk.

💖 DESCRIPTION 💖

Okay so this function does some fast chicanery — literally the source says "fast chicanery" — to return the value of the mask, which is really only used for boolean tests. The status_error_len doesn't need to be shifted because it begins at offset zero. No cap, that's the whole tea. 🍓
