t4vf_fl_pkt_align(9)

πŸ“¦ version 7.3.1, in nixpkgs unstable

πŸ’– t4vf_fl_pkt_align πŸ’–

okay bestie, welcome to the Kernel API Manual, section 9 β€” yes we're in the deep kernel-lore part of the group chat today, and honestly? this one's a little chaotic. buckle up πŸŽ€


✨ NAME ✨

t4vf_fl_pkt_align β€” the function that returns the fl packet alignment. that's it. that's the whole vibe check. πŸ¦‹


🌸 SYNOPSIS 🌸

int t4vf_fl_pkt_align (struct adapter *adapter );

like, one function, one argument, no drama (the adapter has some drama, but that's between us) πŸ’…


🫢 ARGUMENTS 🫢

  • adapter β€” the adapter. that's your whole param list, icon, no notes. 😌

🧚 DESCRIPTION 🧚

okay so here's the lore, and it's giving "hardware family tree that nobody asked for" 😭

T4 has a single field to specify the packing and padding boundary. one field. one single solitary field. iconic minimalist behavior honestly. ⭐

but then T5 onwards has separate fields for this β€” so the alignment for next packet offset is the maximum of these two. two fields, one answer, lowkey math. πŸ”₯

and then T6 shows up and changes the Ingress Padding Boundary Shift, so at this point it's all a mess πŸ’€ and the manpage itself says it's best if we put this in low-level Common Code ... and like, yeah. yeah it is. respect the mess. πŸ™ˆ

no cap, the original literally calls it "a mess" and honestly that's the most honest kernel documentation has ever been. πŸŽ€

okay and for the cute sign-off moment: this page lives at ./drivers/net/ethernet/chelsio... (source/version biz πŸ’–) and it's dated October 2026 β€” so mark your calendars bestie, this manpage is from the future and it's still explaining T4/T5/T6 padding boundaries. periodt. πŸ“βœ¨
