We would cache ether dst pointer on input in br_handle_frame_finish but after the neigh suppress code that could lead to a stale pointer since both ipv4 and ipv6 suppress code do pskb_may_pull. This means we have to always reload it after the suppress code so there's no point in having it cached just retrieve it directly.

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.
