In the current processing logic, when xdp_redirect occurs, it transmits the xdp frame based on napi. If napi of the peer veth is not ready, the veth will drop the packets. This doesn't meet our expectations. In this context, we enable napi of the peer veth automatically when the veth loads the xdp. Then if the veth unloads the xdp, we need to correctly judge whether to disable napi of the peer veth, because the peer veth may have loaded xdp, or even the user has enabled GRO.

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.
