The NetDIM library, currently leveraged by an array of NICs, delivers
excellent acceleration benefits. Nevertheless, NICs vary significantly
in their dim profile list prerequisites.
Specifically, virtio-net backends may present diverse sw or hw device
implementation, making a one-size-fits-all parameter list impractical.
On Alibaba Cloud, the virtio DPU's performance under the default DIM
profile falls short of expectations, partly due to a mismatch in
parameter configuration.
I also noticed that ice/idpf/ena and other NICs have customized
profilelist or placed some restrictions on dim capabilities.
Motivated by this, I tried adding new params for "ethtool -C" that provides
a per-device control to modify and access a device's interrupt parameters.
Usage
========
1. Query the currently customized list of the device
$ ethtool -c ethx
...
rx-eqe-profs:
{.usec = 1, .pkts = 256, .comps = 0,},
{.usec = 8, .pkts = 256, .comps = 0,},
{.usec = 64, .pkts = 256, .comps = 0,},
{.usec = 128, .pkts = 256, .comps = 0,},
{.usec = 256, .pkts = 256, .comps = 0,}
rx-cqe-profs: n/a
tx-eqe-profs: n/a
tx-cqe-profs: n/a
2. Tune
$ ethtool -C ethx rx-eqe-profs 1,1,0_2,2,0_3,3,0_4,4,0_5,5,0
$ ethtool -c ethx
...
rx-eqe-profs:
{.usec = 1, .pkts = 1, .comps = 0,},
{.usec = 2, .pkts = 2, .comps = 0,},
{.usec = 3, .pkts = 3, .comps = 0,},
{.usec = 4, .pkts = 4, .comps = 0,},
{.usec = 5, .pkts = 5, .comps = 0,}
rx-cqe-profs: n/a
tx-eqe-profs: n/a
tx-cqe-profs: n/a
3. Hint
If the device does not support some type of customized dim
profiles, the corresponding "n/a" will display.
