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:
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.
Hao Chen (6):
