In network congestion, instead of pausing all traffic on link PFC allows user to selectively pause traffic according to its class. This series of patches add support of PFC for RVU netdev drivers. Patch1 adds support to disable pause frames by default as with PFC user can enable either PFC or 802.3 pause frames. Patch2&3 adds resource management support for flow control and configures necessary registers for PFC. Patch4 adds dcb ops registration for netdev drivers. V2 changes: Fix compilation error by exporting required symbols 'otx2_config_pause_frm' Hariprasad Kelam (3): octeontx2-af: Don't enable Pause frames by default octeontx2-af: Flow control resource management octeontx2-pf: PFC config support with DCBx Sunil Kumar Kori (1): octeontx2-af: Priority flow control configuration support .../net/ethernet/marvell/octeontx2/af/cgx.c | 247 +++++++++++++----- .../net/ethernet/marvell/octeontx2/af/cgx.h | 13 + .../marvell/octeontx2/af/lmac_common.h | 10 + .../net/ethernet/marvell/octeontx2/af/mbox.h | 19 ++ .../net/ethernet/marvell/octeontx2/af/rpm.c | 223 ++++++++++++---- .../net/ethernet/marvell/octeontx2/af/rpm.h | 30 +++ .../net/ethernet/marvell/octeontx2/af/rvu.h | 3 + .../ethernet/marvell/octeontx2/af/rvu_cgx.c | 117 ++++++++- .../ethernet/marvell/octeontx2/af/rvu_nix.c | 16 +- .../ethernet/marvell/octeontx2/nic/Makefile | 3 + .../marvell/octeontx2/nic/otx2_common.c | 18 +- .../marvell/octeontx2/nic/otx2_common.h | 12 + .../marvell/octeontx2/nic/otx2_dcbnl.c | 170 ++++++++++++ .../marvell/octeontx2/nic/otx2_flows.c | 50 +++- .../ethernet/marvell/octeontx2/nic/otx2_pf.c | 26 +- .../ethernet/marvell/octeontx2/nic/otx2_vf.c | 24 +- 16 files changed, 836 insertions(+), 145 deletions(-) create mode 100644 drivers/net/ethernet/marvell/octeontx2/nic/otx2_dcbnl.c -- 2.17.1
