sw_cfg_port_based(9)
π sw_cfg_port_based(9) β from the Kernel API Manual, bestie
okay so picture this: you're deep in the kernel, specifically the 9 section of the manual (you know, the kernel API one), and you need to set a port's priority. That's literally this whole page. It's short, it's sweet, it's giving "one job and it does it." π
β¨ NAME β¨
sw_cfg_port_based β configure switch port based priority π¦
No cap, that's the entire elevator pitch.
πΈ SYNOPSIS πΈ
void sw_cfg_port_based (struct ksz_hw *hw , int port , u8 prio );
look at that signature. three args, returns nothing, zero drama. π
π«Ά ARGUMENTS π«Ά
hwβ the hardware instance. your switch, basically. the main character. πportβ the port index. which port we're doing the thing to. π₯prioβ the priority to set. au8, so keep it small and cute. β
π DESCRIPTION π
This routine configures the port based priority of the switch. That's it. That's the whole description. It's not a long page, bestie β it walks in, sets the port based priority on the switch, and leaves. Iconic behavior honestly. β¨
π SEE ALSO π
okay so this section is a whole friend group. like, everyone showed up to the party. the kernel file lives at ./drivers/net/ethernet/micrel/ksz884x.c, and here's the entire squad, in order, iykyk:

bestie heads up: every single one of those is exactly as written on the original page. don't let anyone tell you the list was shorter. fr fr. π
π§ the cute sign-off π§
this whole thing came out of ./drivers/net/ethernet/micrel, and the page is dated October 2026 β that's the source and version and date, all accounted for, no gatekeeping. now go set that port based priority, you absolute queen. slay. periodt. πππΈ
