[PATCH v5 0/9] Add vhost-user support to passt (part 1)

[Laurent Vivier <lvivier@redhat.com>]

v5:
  - add a patch to cleanup before change:
    udp: little cleanup in udp_update_hdrX() to prepare future changes
  - see detailed v5 history log in each patch

v4:
  - rebase
  - see detailed v4 history log in each patch

v3:
  - add a patch that has been extracted from:
    "tcp: extract buffer management from tcp_send_flag()"
    -> "tcp: Introduce ipv4_fill_headers()/ipv6_fill_headers()"
  - see detailed v3 history log in each patch
  - I didn't address the alignment problem when we provide a pointer
    to a sub-structure in the internal buffer structure.
    (for the last patches of the series).

v2 comparing to vhost-user full part:
  - part 1 includes only preliminary patches (checksum, iovec, cleanup)
  - see detailed v2 history log in each patch.

Full series v1 available at:
