Guangbin Huang says: ==================== ethtool: add support to set/get tx copybreak buf size and rx buf len This series add support to set/get tx copybreak buf size and rx buf len via ethtool and hns3 driver implements them. Tx copybreak buf size is used for tx copybreak feature which for small size packet or frag. Use ethtool --get-tunable command to get it, and ethtool --set-tunable command to set it, examples are as follow: 1. set tx spare buf size to 102400: $ ethtool --set-tunable eth1 tx-buf-size 102400 2. get tx spare buf size: $ ethtool --get-tunable eth1 tx-buf-size tx-buf-size: 102400 Rx buf len is buffer length of each rx BD. Use ethtool -g command to get it, and ethtool -G command to set it, examples are as follow: 1. set rx buf len to 4096 $ ethtool -G eth1 rx-buf-len 4096 2. get rx buf len $ ethtool -g eth1 ... RX Buf Len: 4096 Change log: V5 -> V6 1.Fix compile error for divers/s390. V4 -> V5 1.Change struct ethtool_ringparam_ext to kernel_ethtool_ringparam. 2.change "__u32 rx_buf_len" to "u32 rx_buf_len". V3 -> V4 1.Fix a few allmodconfig compile warning. 2.Add more '=' synbol to ethtool-netlink.rst to refine format. 3.Move definement of struct ethtool_ringparam_ext to include/linux/ethtool.h. 4.Move related modify of rings_fill_reply() from patch 4/6 to patch 3/6. V2 -> V3 1.Remove documentation for tx copybreak buf size, there is description for it in userspace ethtool. 2.Move extending parameters for get/set_ringparam function from patch3/6 to patch 4/6. V1 -> V2 1.Add documentation for rx buf len and tx copybreak buf size. 2.Extend structure ringparam_ext for extenal ring params. 3.Change type of ETHTOOL_A_RINGS_RX_BUF_LEN from NLA_U32 to NLA_POLICY_MIN(NLA_U32, 1). 4.Add supported_ring_params in ethtool_ops to indicate if support external params. ==================== Signed-off-by: David S.

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.
