[PATCH v6 0/8] Add vhost-user support to passt (part 2)

[Laurent Vivier <lvivier@redhat.com>]

Extract buffers management code from tcp.c and move
it to tcp_buf.c
tcp.c keeps all the generic code and will be also used by
the vhost-user functions.

Also compare mode to MODE_PASTA, as we will manage vhost-user
mode (MODE_VU) like MODE_PASST.

v6:
  - reorder declarations, align summing, add curly brackets
  - rename tap_handler_all() to tap_handler()
  - rename packet_add_all_do() to tap_add_packet
    and remove func and line.
  - rename pool_flush_all() to tap_flush_pools()
  - rename tcp_fill_flag_header() to tcp_prepare_flags()
  - set optlen to 0 in tcp_prepare_flags()

v5:
  - remove:
    [PATCH v4 01/10] tcp: inline tcp_l2_buf_fill_headers()
  - merge
    [PATCH v4 09/10] tcp: remove tap_hdr parameter
    into  tcp: extract buffer management from tcp_send_flag()
  - update comments

v4:
  - remove "tcp: extract buffer management from tcp_conn_tap_mss()"
    as the MSS size can be the same between socket and vhost-user.
  - rename tcp_send_flag() and tcp_data_from_sock() to
    tcp_buf_send_flag() and tcp_buf_data_from_sock()

v3:
  - add 3 new patches
    tap: use in->buf_size rather than sizeof(pkt_buf)
    tcp: remove tap_hdr parameter
    iov: remove iov_copy()

v2:
  - compare to MODE_PASTA in conf_open_files() too
  - move taph out of udp_update_hdr4()/udp_update_hdr6()

Laurent Vivier (8):
  tcp: extract buffer management from tcp_send_flag()
  tcp: move buffers management functions to their own file
  tap: refactor packets handling functions
  udp: refactor UDP header update functions
  udp: rename udp_sock_handler() to udp_buf_sock_handler()
  vhost-user: compare mode MODE_PASTA and not MODE_PASST
  iov: remove iov_copy()
  tap: use in->buf_size rather than sizeof(pkt_buf)
