Merge branch 'skbuff-micro-optimize-flow-dissection'
Alexander Lobakin says:
====================
skbuff: micro-optimize flow dissection
This little number makes all of the flow dissection functions take
raw input data pointer as const (1-5) and shuffles the branches in
__skb_header_pointer() according to their hit probability.
The result is +20 Mbps per flow/core with one Flow Dissector pass
per packet. This affects RPS (with software hashing), drivers that
use eth_get_headlen() on their Rx path and so on.
From v2 [1]:
- reword some commit messages as a potential fix for NIPA;
- no functional changes.
From v1 [0]:
- rebase on top of the latest net-next. This was super-weird, but
I double-checked that the series applies with no conflicts, and
then on Patchwork it didn't;
- no other changes.
