We can remove a conditional test in gro_list_prepare() by comparing vlan_all fields of the two skbs. Notes: While comparing the vlan_proto is not strictly needed, because part of the following compare_ether_header() call, using 32bit word is actually faster than using 16bit values. napi_reuse_skb() makes sure to clear skb->vlan_all, as it already calls __vlan_hwaccel_clear_tag() Signed-off-by: Eric Dumazet <edumazet@google.com> Acked-by: Martin KaFai Lau <martin.lau@kernel.org> Signed-off-by: Jakub Kicinski <kuba@kernel.org>
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.
