When available, translate IP and TCP/UDP port address modify actions to internal hardware specification and offload the flow to hardware. Original work by Shagun Agrawal Signed-off-by: Rahul Lakkireddy --- v3: - No changes. v2: - No changes. v1 changes since RFC v2: - Re-based to tip. - Updated all instances of fw_filter_wr to new fw_filter2_wr and removed fw_filter_wr. - Ensure correct ULP type is set when offloading NAT actions. - Returning appropriate RTE_FLOW_ERROR_TYPE_ACTION error if a corresponding valid flow pattern item for the header rewrite action is not found. - Updated release notes. doc/guides/rel_notes/release_18_11.rst | 4 +- drivers/net/cxgbe/base/common.h | 1 + drivers/net/cxgbe/base/t4_msg.h | 1 + drivers/net/cxgbe/base/t4fw_interface.h | 23 ++- drivers/net/cxgbe/cxgbe_filter.c | 37 +++-- drivers/net/cxgbe/cxgbe_filter.h | 23 +++ drivers/net/cxgbe/cxgbe_flow.c | 178 +++++++++++++++++++++++- drivers/net/cxgbe/cxgbe_main.c | 10 ++ 8 files changed, 265 insertions(+), 12 deletions(-) diff --git a/doc/guides/rel_notes/release_18_11.rst b/doc/guides/rel_notes/release_18_11.rst index 2b4808226..9a135c89c 100644 --- a/doc/guides/rel_notes/release_18_11.rst +++ b/doc/guides/rel_notes/release_18_11.rst @@ -59,7 +59,9 @@ New Features Flow API support has been enhanced for CXGBE Poll Mode Driver to offload: * Match items: destination MAC address. - * Action items: push/pop/rewrite vlan header. + * Action items: push/pop/rewrite vlan header, rewrite IP addresses in + outermost IPv4/IPv6 header, rewrite port numbers in outermost TCP/UDP + header. * **Added a devarg to use the latest supported vector path in i40e.** A new devarg ``use-latest-supported-vec`` was introduced to allow users to diff --git a/drivers/net/cxgbe/base/common.h b/drivers/net/cxgbe/base/common.h index d9f74d995..fd2006682 100644 --- a/drivers/net/cxgbe/base/common.h +++ b/drivers/net/cxgbe/base/common.h @@ -271,6 +271,7 @@ struct adapter_params { bool ulptx_memwrite_dsgl; /* use of T5 DSGL allowed */ u8 fw_caps_support; /* 32-bit Port Capabilities */ + u8 filter2_wr_support; /* FW support for FILTER2_WR */ }; /* Firmware Port Capabilities types. diff --git a/drivers/net/cxgbe/base/t4_msg.h b/drivers/net/cxgbe/base/t4_msg.h index 2128da64f..6494f1827 100644 --- a/drivers/net/cxgbe/base/t4_msg.h +++ b/drivers/net/cxgbe/base/t4_msg.h @@ -32,6 +32,7 @@ enum CPL_error { enum { ULP_MODE_NONE = 0, + ULP_MODE_TCPDDP = 5, }; enum { diff --git a/drivers/net/cxgbe/base/t4fw_interface.h b/drivers/net/cxgbe/base/t4fw_interface.h index e2d2ee897..b4c95c588 100644 --- a/drivers/net/cxgbe/base/t4fw_interface.h +++ b/drivers/net/cxgbe/base/t4fw_interface.h @@ -61,6 +61,7 @@ enum fw_wr_opcodes { FW_ETH_TX_PKTS_WR = 0x09, FW_ETH_TX_PKT_VM_WR = 0x11, FW_ETH_TX_PKTS_VM_WR = 0x12, + FW_FILTER2_WR = 0x77, FW_ETH_TX_PKTS2_WR = 0x78, }; @@ -165,7 +166,7 @@ enum fw_filter_wr_cookie { FW_FILTER_WR_EINVAL, }; -struct fw_filter_wr { +struct fw_filter2_wr { __be32 op_pkd; __be32 len16_pkd; __be64 r3; @@ -195,6 +196,19 @@ struct fw_filter_wr { __be16 fpm; __be16 r7; __u8 sma[6]; + __be16 r8; + __u8 filter_type_swapmac; + __u8 natmode_to_ulp_type; + __be16 newlport; + __be16 newfport; + __u8 newlip[16]; + __u8 newfip[16]; + __be32 natseqcheck; + __be32 r9; + __be64 r10; + __be64 r11; + __be64 r12; + __be64 r13; }; #define S_FW_FILTER_WR_TID 12 @@ -300,6 +314,12 @@ struct fw_filter_wr { #define S_FW_FILTER_WR_MATCHTYPEM 0 #define V_FW_FILTER_WR_MATCHTYPEM(x) ((x) << S_FW_FILTER_WR_MATCHTYPEM) +#define S_FW_FILTER2_WR_NATMODE 5 +#define V_FW_FILTER2_WR_NATMODE(x) ((x) << S_FW_FILTER2_WR_NATMODE) + +#define S_FW_FILTER2_WR_ULP_TYPE 0 +#define V_FW_FILTER2_WR_ULP_TYPE(x) ((x) << S_FW_FILTER2_WR_ULP_TYPE) + /****************************************************************************** * C O M M A N D s *********************/ @@ -655,6 +675,7 @@ enum fw_params_param_dev { FW_PARAMS_PARAM_DEV_FWREV = 0x0B, /* fw version */ FW_PARAMS_PARAM_DEV_TPREV = 0x0C, /* tp version */ FW_PARAMS_PARAM_DEV_ULPTX_MEMWRITE_DSGL = 0x17, + FW_PARAMS_PARAM_DEV_FILTER2_WR = 0x1D, }; /* diff --git a/drivers/net/cxgbe/cxgbe_filter.c b/drivers/net/cxgbe/cxgbe_filter.c index dcb1dd03e..b876abf43 100644 --- a/drivers/net/cxgbe/cxgbe_filter.c +++ b/drivers/net/cxgbe/cxgbe_filter.c @@ -89,6 +89,9 @@ int validate_filter(struct adapter *adapter, struct ch_filter_specification *fs) if (fs->val.iport >= adapter->params.nports) return -ERANGE; + if (!fs->cap && fs->nat_mode && !adapter->params.filter2_wr_support) + return -EOPNOTSUPP; + return 0; } @@ -627,6 +630,7 @@ void clear_filter(struct filter_entry *f) /** * t4_mk_filtdelwr - create a delete filter WR + * @adap: adapter context * @ftid: the filter ID * @wr: the filter work request to populate * @qid: ingress queue to receive the delete notification @@ -634,10 +638,14 @@ void clear_filter(struct filter_entry *f) * Creates a filter work request to delete the supplied filter.
