Merge branch 'ethtool-provide-the-dim-profile-fine-tuning-channel'
Heng Qi says:
====================
ethtool: provide the dim profile fine-tuning channel
The NetDIM library provides excellent acceleration for many modern
network cards. However, the default profiles of DIM limits its maximum
capabilities for different NICs, so providing a way which the NIC can
be custom configured is necessary.
Currently, the way is based on the commonly used "ethtool -C".
For example,
on the server side, the virtio-net NIC with rx dim enabled has 8
queues and runs nginx.
The client uses the following command to send traffic to the server:
./wrk http://server_ip:80 -c 64 -t 5 -d 30
Then adjust the default rx-profile for server dim to
{.usec = 1, .pkts = 256, .comps = n/a,},
{.usec = 8, .pkts = 256, .comps = n/a,},
{.usec = 30, .pkts = 256, .comps = n/a,},
{.usec = 64, .pkts = 256, .comps = n/a,},
{.usec = 128, .pkts = 256, .comps = n/a,}
The server PPS is improved by 20%+.
