π i40e_get_stats_count(9) β Kernel API Manual
okay bestie, welcome to the glow-up of the i40e_get_stats_count page from the Kernel API Manual. it's a tiny function with a big boundary rule, and honestly it's giving "short but iconic." β¨
π NAME
i40e_get_stats_count β returns the stats count for a device, periodt π
β¨ SYNOPSIS
int i40e_get_stats_count (struct net_device *netdev );
π¦ ARGUMENTS
netdevβ the netdev you want the count for π«Ά that's it, that's the whole input.
π₯ DESCRIPTION
so it returns the total number of statistics for this netdev. easy enough, right? ok but here's the part where you need to listen, bestie π
even though this is literally a function (a real one, with a return value and everything), the count for a specific netdev must never change. like, ever. not a vibe check, a hard rule. π
you can base the count on static values β stuff like the maximum number of queues, or the device type. that's fine, that slays. π
but the API for obtaining stats is *not* safe against changes based on non-static values, so do not do that. examples of the forbidden nonsense: the current number of queues, or runtime flags. nope nope nope, keep those out of your count π
and one more thing β if a statistic isn't always enabled, return it as part of the count anyways. always return its string, and report its value as zero. lowkey elegant, highkey mandatory. β
fr fr: constant count, always-present string, zero for the value. that's the whole assignment. π
