Subject: [dpdk-dev] [PATCH 00/15] remove mbuf userdata
Date: Mon, 26 Oct 2020 06:20:50 +0100	[thread overview]
Message-ID: <20201026052105.1561859-1-thomas@monjalon.net> (raw)

The mbuf field userdata (aliased as udata64)
was announced to be removed for two reasons:
  - applications, libraries and drivers used the same field
    for different purposes, with a risk of usage conflict.
  - this field always used 8 bytes even if unneeded

Some dynamic fields are created when needed to replace
the big static userdata field.
As a consequence, 8 bytes can be re-allocated to dynamic fields.

This mbuf layout change is important to allow adding more features
(consuming more dynamic fields) during the next year.

Thomas Monjalon (15):
  examples: enclose DPDK includes with angle brackets
  kni: move header file from EAL
  mbuf: fix typo in dynamic field convention note
  node: switch IPv4 metadata to dynamic mbuf field
  security: switch metadata to dynamic mbuf field
  event/sw: switch test counter to dynamic mbuf field
  net/ark: ignore user data
  net/bnxt: switch CFA code to dynamic mbuf field
  net/vmxnet3: switch MSS hint to dynamic mbuf field
  test/distributor: switch sequence to dynamic mbuf field
  test/graph: switch user data to dynamic mbuf field
  app/eventdev: switch flow ID to dynamic mbuf field
  examples/bbdev: switch to dynamic mbuf field
  examples/rxtx_callbacks: switch to dynamic mbuf field
  mbuf: remove userdata field
