i40e_fd_handle_status(9)
π i40e_fd_handle_status(9) β the i40e kernel API manual, bestie edition β¨
okay so real quick: this whole page lives in the <pink>i40e_fd_handle_status</pink> section of the Kernel API Manual (section 9, the kernel one, iykyk) β and we're about to make it make sense. no cap.
πΈ NAME
i40e_fd_handle_status β bestie, it checks the Programming Status for FD. that's the whole vibe check right there π
β¨ SYNOPSIS
void i40e_fd_handle_status (struct i40e_ring *rx_ring , u64 qword0_raw ,
u64 qword1 , u8 prog_id );
likeβ¦ it returns nothing (void), it takes four things, and it's just out here doing its little job π«Ά
π ARGUMENTS
rx_ringβ the Rx ring for this descriptor. yes queen, the ring the descriptor belongs to πqword0_rawβ qword0. that's it. that's the description. raw and unfiltered, we love that for it πqword1β qword1 afterle_to_cpu. so it's already been converted, don't come for it πprog_idβ the id that was originally used for programming. the og id, the one from the start β
π₯ DESCRIPTION
okay so here's the tea β β this function is literally here to verify if the FD programming or invalidation that SW (that's software, bestie) requested from the HW (hardware, obviously π) actually succeeded or not, and then to take actions accordingly. that's it. that's the whole main character energy.
like it's giving "did the thing work or did it flop" and either way it handles it. no notes, periodt π

ngl that's a lot of i40e functions but every single one of them ate and left no crumbs π₯
and that's the whole page bestie!! one last thing before you go β this whole thing comes from ./drivers/net/ethernet/intel/i40e, dated October 2026, and it's filed under i40e_fd_handle_status(9). mwah, love u, go read some source code π§π π
