idpf_tx_set_tstamp_desc(9)
π idpf_tx_set_tstamp_desc β¨
okay so this is a page straight out of the Kernel API Manual, and bestie, it is tiny but it is important. Like, it's a whole one-function moment and it's giving "small but mighty." π
πΈ NAME πΈ
idpf_tx_set_tstamp_desc β genuinely just here to Set the Tx descriptor fields needed to generate PHY Tx timestamp. That's the whole job. That's the assignment. And it ate. π
π¦ SYNOPSIS π¦
void idpf_tx_set_tstamp_desc (union idpf_flex_tx_ctx_desc *ctx_desc ,
u32 idx );
void return, two arguments, no drama. she's lowkey minimal and I respect it. β¨
π ARGUMENTS π
ctx_descβ the Context descriptor. this is the thing you're poking at, bestie. the canvas. the main character of the operation π¨idxβ the Index of the Tx timestamp latch. which latch, specifically? this one. this number right here. no cap. π’
π§ SEE ALSO π§
first up, the home base, the kernel file that this whole situation lives in:
./drivers/net/ethernet/intel/idpf/idpf_txrx.c
and thenβ¦ okay so the SEE ALSO section on this page is not playing around. it's a whole friend group. a whole extended family reunion. grab a snack, we're going through everyone. π«Ά

like I said. the whole group chat. every single one of them showed up to the function. ππ
heads up bestie: this whole page is only about setting those Tx descriptor fields for the PHY Tx timestamp β nothing more, nothing less. don't go reading extra powers into it. π
and that's the page!! mwah π this little number came out of ./drivers/net/ethernet/intel/idpf, dated October 2026 β so yes she's an October girlie πβ¨, and she's filed under idpf_tx_set_tstamp_desc(9) in the Kernel API Manual, periodt. π¦
