Subject: [PATCH net-next v2 0/5] nfp: DMA flags, adjust head and fixes

Hi!

This series takes advantage of Alex's DMA_ATTR_SKIP_CPU_SYNC to make 
XDP packet modifications "correct" from DMA API point of view.  It 
also allows us to parse the metadata before we run XDP at no additional
DMA sync cost.  That way we can get rid of the metadata memcpy, and 
remove the last upstream user of bpf_prog->xdp_adjust_head.

David's patch adds a way to read capabilities from the management
firmware.

There are also two net-next fixes.  Patch 4 which fixes what seems to
be a result of a botched rebase on my part.  Patch 5 corrects locking
when state of ethernet ports is being refreshed.

v2: sync rx buffers before giving them to the card (Alex)

David Brunecz (1):
  nfp: add NSP routine to get static information

Jakub Kicinski (4):
  nfp: make use of the DMA_ATTR_SKIP_CPU_SYNC flag
  nfp: parse metadata prepend before XDP runs
  nfp: fix free list buffer size reporting
  nfp: remove the refresh of all ports optimization
