i40e_disable_pf_switch_lb(9)
💖 i40e_disable_pf_switch_lb — Kernel API Manual ✨
okay so bestie, welcome to the manual page for i40e_disable_pf_switch_lb, living in the Kernel API Manual. That's the whole header, we're moving on 🎀
🌸 NAME 🌸
i40e_disable_pf_switch_lb
and that's… it. the original page leaves the description field completely empty. no notes, no summary, just the name and vibes. honestly? minimalism. main character energy. we respect it 💅
✨ SYNOPSIS ✨
void i40e_disable_pf_switch_lb (struct i40e_pf *pf );like, exactly that. void, then the name, then one single argument in parens. no cap 🫶
🦋 ARGUMENTS 🦋
pf— pointer to the PF structure. that's it, that's the whole argument list. it's giving "one job, one pointer" 👑
💜 DESCRIPTION 💜
so what does it do? the page says, and I quote: disable switch loop back or die - no point in a return value. 😭
like yes, that's genuinely the description. it disables switch loopback, and it has no return value — because, per the original, there's no point in one. so don't go assigning its result to anything, there isn't one to assign. void means void, bestie 💀
the "or die" phrasing is straight from the original text — dramatic? absolutely. keep it in mind: there's no error code coming back to you, so don't go looking for one 🔥
🌈 SEE ALSO 🌈
the kernel file it lives in: ./drivers/net/ethernet/intel/i40e/i40e_main.c — that's the source of truth, go read it if you want the real tea 🍓
and now… the group chat. literally every single friend it's linked to, in order, no one left on read 💖:
