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 drivers/net/ethernet/netronome/nfp/Makefile | 1 + drivers/net/ethernet/netronome/nfp/nfp_main.c | 7 ++ drivers/net/ethernet/netronome/nfp/nfp_net.h | 9 +- .../net/ethernet/netronome/nfp/nfp_net_common.c | 126 ++++++++++++--------- .../net/ethernet/netronome/nfp/nfp_net_ethtool.c | 13 ++- drivers/net/ethernet/netronome/nfp/nfp_net_main.c | 67 +++++++---- drivers/net/ethernet/netronome/nfp/nfpcore/nfp.h | 1 + .../net/ethernet/netronome/nfp/nfpcore/nfp_nsp.c | 7 ++ .../net/ethernet/netronome/nfp/nfpcore/nfp_nsp.h | 24 ++++ .../ethernet/netronome/nfp/nfpcore/nfp_nsp_cmds.c | 89 +++++++++++++++ 10 files changed, 266 insertions(+), 78 deletions(-) create mode 100644 drivers/net/ethernet/netronome/nfp/nfpcore/nfp_nsp_cmds.c -- 2.11.0
