Milk-V Jupiter Linux kernel
cd275c236b
Send and complete XSK pool frames within TX NAPI context. NAPI context
is triggered by ndo_xsk_wakeup.
Test results with A53 1.2GHz:
xdpsock txonly copy mode, 64 byte frames:
pps pkts 1.00
tx 284,409 11,398,144
Two CPUs with 100% and 10% utilization.
xdpsock txonly zero-copy mode, 64 byte frames:
pps pkts 1.00
tx 511,929 5,890,368
Two CPUs with 100% and 1% utilization.
xdpsock l2fwd copy mode, 64 byte frames:
pps pkts 1.00
rx 248,985 7,315,885
tx 248,921 7,315,885
Two CPUs with 100% and 10% utilization.
xdpsock l2fwd zero-copy mode, 64 byte frames:
pps pkts 1.00
rx 254,735 3,039,456
tx 254,735 3,039,456
Two CPUs with 100% and 4% utilization.
Packet rate increases and CPU utilization is reduced in both cases.

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.
