π t4_read_rss_vf_config(9) β the Kernel API Manual glow-up β¨
ok so this is a page straight out of the Kernel API Manual, section 9, and honestly? it's a little one but it serves. bestie, we're reading a VF RSS Configuration Table and i'm gonna walk you through it like we're decoding a group chat screenshot π«Ά
β¨ NAME β¨
t4_read_rss_vf_config β read VF RSS Configuration Table π
πΈ SYNOPSIS πΈ
void t4_read_rss_vf_config (struct adapter *adapter , unsigned int index
, u32 *vfl , u32 *vfh , bool sleep_ok );
it's giving "void, no return value, we just vibe and fill your pointers" β¨
π ARGUMENTS π
adapterβ the adapter. literally the whole personality of the call π¦indexβ the entry in the VF RSS table to read. yes you have to pick one, it's not a buffet πvflβ where to store the returned VFL π₯vfhβ where to store the returned VFH π₯sleep_okβ iftruewe may sleep while awaiting command completion π΄ no cap, if it'strueyou're allowed to nap on the job
π DESCRIPTION π
Reads the VF RSS Configuration Table at the specified index and returns the (VFL, VFH) values found there. that's it. that's the whole plot π in at an index, out come VFL and VFH, dropped right into the pointers you handed over. iconic, efficient, no notes π

like i said. whole friend group. tag them all in the chat or don't bother π
tiny reminder bestie: this page drops the manual name Kernel API Manual and section 9 up top, and the footer says the source is./drivers/net/ethernet/chelsio...dated October 2026, tied tot4_read_rss_vf_config(9). π§
and that's the page!! short, sweet, (VFL, VFH) out, no drama β¨ go read your RSS tables responsibly, mwah ππ
