It is not so generic. Use the new dynamic mbuf field and flags to handle protocol extraction. Then the metadata is very clean, only network protocol fields extracted by defined offset, and its type will be indicated by related ol_flags. Signed-off-by: Haiyue Wang --- v7: - Change the log level from ERR to DEBUG for a successful registration, ERR is used to develop firstly. v6: - Don't need to register all flags when if one dev_args is set, register it as required. v5: - Remove the '_OL/_ol' in dynamic mbuf flag to make the variable clean. v4: - Include the 'rte_pmd_ice.h' header in ICE source as needed, reduce its compile scope. v3: - Use the conventions name "rte_net__dynfield_" since it is defined in a in PMD. - Add helpers API for easiy access. v2: - disable the protocol extraction if failed to register some ol_flags - rewrite the commit message doc/api/doxy-api-index.md | 1 + doc/api/doxy-api.conf.in | 1 + doc/guides/nics/ice.rst | 14 +- drivers/net/ice/ice_ethdev.c | 82 +++++- drivers/net/ice/ice_ethdev.h | 9 + drivers/net/ice/ice_rxtx.c | 91 +++++-- drivers/net/ice/ice_rxtx.h | 1 - drivers/net/ice/rte_pmd_ice.h | 328 +++++++++++++++--------- drivers/net/ice/rte_pmd_ice_version.map | 12 + 9 files changed, 386 insertions(+), 153 deletions(-) diff --git a/doc/api/doxy-api-index.md b/doc/api/doxy-api-index.md index 28a5dd37e..dff496be0 100644 --- a/doc/api/doxy-api-index.md +++ b/doc/api/doxy-api-index.md @@ -42,6 +42,7 @@ The public API headers are grouped by topics: [KNI] (@ref rte_kni.h), [ixgbe] (@ref rte_pmd_ixgbe.h), [i40e] (@ref rte_pmd_i40e.h), + [ice] (@ref rte_pmd_ice.h), [bnxt] (@ref rte_pmd_bnxt.h), [dpaa] (@ref rte_pmd_dpaa.h), [dpaa2] (@ref rte_pmd_dpaa2.h), diff --git a/doc/api/doxy-api.conf.in b/doc/api/doxy-api.conf.in index d8dafb289..faa3b1593 100644 --- a/doc/api/doxy-api.conf.in +++ b/doc/api/doxy-api.conf.in @@ -12,6 +12,7 @@ INPUT = @TOPDIR@/doc/api/doxy-api-index.md \ @TOPDIR@/drivers/net/dpaa \ @TOPDIR@/drivers/net/dpaa2 \ @TOPDIR@/drivers/net/i40e \ + @TOPDIR@/drivers/net/ice \ @TOPDIR@/drivers/net/ixgbe \ @TOPDIR@/drivers/net/softnic \ @TOPDIR@/drivers/raw/dpaa2_cmdif \ diff --git a/doc/guides/nics/ice.rst b/doc/guides/nics/ice.rst index 933f63480..04af80545 100644 --- a/doc/guides/nics/ice.rst +++ b/doc/guides/nics/ice.rst @@ -82,8 +82,8 @@ Runtime Config Options - ``Protocol extraction for per queue`` - Configure the RX queues to do protocol extraction into ``rte_mbuf::udata64`` - for protocol handling acceleration, like checking the TCP SYN packets quickly. + Configure the RX queues to do protocol extraction into mbuf for protocol + handling acceleration, like checking the TCP SYN packets quickly.
