Let me ask again :

I see two different potential call points :

drivers/net/wireless/intel/iwlwifi/pcie/tx.c:1529:
tso_build_hdr(skb, hdr_page->pos, &tso, data_left, !total_len);
drivers/net/wireless/intel/iwlwifi/queue/tx.c:427:
tso_build_hdr(skb, hdr_page->pos, &tso, data_left, !total_len);

To the best of your knowledge, which one would be used in your case ?

Both are horribly complex, I do not want to spend time studying two
implementations.

Thanks.
