π i40e_setup_rx_descriptors(9) π
okay so bestie, welcome to the kernel API manual β¨ β this one lives in the <pink>Kernel API Manual</pink> section and it's all about setting up your Rx descriptor ring. Let's get into it π
πΈ NAME πΈ
i40e_setup_rx_descriptors β allocate Rx descriptors, bestie. That's it. That's the whole vibe. π
π¦ SYNOPSIS π¦
int i40e_setup_rx_descriptors (struct i40e_ring *rx_ring );
π ARGUMENTS π
rx_ringβ the Rx descriptor ring you wanna set up, like, for one specific queue π. This is the main character of the whole function, no cap.
β DESCRIPTION β
So here's the tea β β this function returns <green>0</green> on success, and a <red>negative</red> value on failure. That's literally it. Fr fr. Not every function needs a whole saga, and this one is refreshingly lowkey about it π«Ά
π SEE ALSO π
buckle up bestie, this list is long and honestly kind of iconic π₯ First, the kernel file this all lives in:

like, yes, that's A LOT of cross-references π but they're all right there in the page and we don't gatekeep here π
and that's the whole page, bestie! mwah π this lil corner of the kernel lives in ./drivers/net/ethernet/intel/i40e, and this particular page is dated October 2026 β so yeah, it's from the future, deal with it π¦ slay, and happy descriptor-allocating πβ¨
