Subject: [PATCH net-next 0/5] ethtool: add support to set/get tx spare buf size and rx buf len
Date: Wed, 25 Aug 2021 14:40:50 +0800 [thread overview]
Message-ID: <1629873655-51539-1-git-send-email-huangguangbin2@huawei.com> (raw)
This series add support to set/get tx spare buf size and rx buf len via
ethtool and hns3 driver implements them.
Tx spare 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
