Subject: [PATCH v5 bpf-next 0/2] introduce xdp_init_buff/xdp_prepare_buff

Introduce xdp_init_buff and xdp_prepare_buff utility routines to initialize
xdp_buff data structure and remove duplicated code in all XDP capable
drivers.

Changes since v4:
- fix xdp_init_buff/xdp_prepare_buff (natural order is xdp_init_buff() first
  and then xdp_prepare_buff())

Changes since v3:
- use __always_inline instead of inline for xdp_init_buff/xdp_prepare_buff
- add 'const bool meta_valid' to xdp_prepare_buff signature to avoid
  overwriting data_meta with xdp_set_data_meta_invalid()
- introduce removed comment in bnxt driver

Changes since v2:
- precompute xdp->data as hard_start + headroom and save it in a local
  variable to reuse it for xdp->data_end and xdp->data_meta in
  xdp_prepare_buff()

Changes since v1:
- introduce xdp_prepare_buff utility routine

Lorenzo Bianconi (2):
  net: xdp: introduce xdp_init_buff utility routine
  net: xdp: introduce xdp_prepare_buff utility routine
