Subject: [PATCH net-next 0/3] validate variable length ll headers

From: Willem de Bruijn <willemb@...gle.com>

Allow device-specific validation of link layer headers. Existing
checks drop all packets shorter than hard_header_len. For variable
length protocols, such packets can be valid.

patch 1 adds header_ops.validate and dev_validate_header
patch 2 implements the protocol specific callback for AX25
patch 3 replaces ll_header_truncated with dev_validate_header

Willem de Bruijn (3):
  net: validate variable length ll headers
  ax25: add link layer header validation function
  packet: validate variable length ll headers
