When neighbour become invalid or destroyed, neigh_invalidate() will be called. neigh->ops->error_report() will be called if the neighbour's state is NUD_FAILED, and seems here is the only use of error_report(). So we can tell that the reason of skb drops in arp_error_report() is SKB_DROP_REASON_NEIGH_FAILED. Replace kfree_skb() used in arp_error_report() with kfree_skb_reason().

Linux kernel
============
There are several guides for kernel developers and users. These guides can
be rendered in a number of formats, like HTML and PDF. Please read
Documentation/admin-guide/README.rst first.
In order to build the documentation, use ``make htmldocs`` or
``make pdfdocs``. The formatted documentation can also be read online at:
https://www.kernel.org/doc/html/latest/
There are various text files in the Documentation/ subdirectory,
several of them using the Restructured Text markup notation.
Please read the Documentation/process/changes.rst file, as it contains the
requirements for building and running the kernel, and information about
the problems which may result by upgrading your kernel.
