rx pause frame
EthApp> pause 0 rx
Based on 50% line rate, calculate how many packets hanged per pause frame
Configure transmit number of packets and then one pause frame from test
port
Check forwarded rate just 50% and difference smaller than 0.1%
- Case: ethtool_tx_pause
Description: check userspace sample can configure port tx pause setting
Command / instruction:
After receive burst of packets, sleep a while for slow down
usleep(10);
Rebuild sample and start userspace ethtool sample with two ports bound
ethtool -c f -n 4
Enable port 0 wiht transmit pause frame
EthApp> pause 0 tx
Send packets with line rate from tester port
Enable tester port link control, transmit speed will also dropped
After few seconds stop transmit, check tester port received packets more
than transmitted.

>
> Further enhancements to the userspace ethtool implementation that was
> submitted in 2.1 and packaged as a self-contained sample application.
> Implements an rte_ethtool shim layer based on rte_ethdev API, along
> with a command prompt driven demonstration application.

> This patchset depends on:
> * http://dpdk.org/dev/patchwork/patch/8070/
>
> v9:
> * Merged in upstream external lib dependency
> * Added sanity check to shim MTU set function
> * Added example to example/Makefile
> * Rebased to latest master
>
> v8:
> * Rebased to latest origin/master
>
> v7:
> * Ringparam printouts wrong way round
> * Ringparam help message corrections
> * Use __rte_unused instead of __attribute__((unused))
> * Allow Jumbo-sized MTUs
> * Documentation style and spelling changes
>
> v6:
> * Fixed hang when run with zero available ports
> * Fixed incorrect sanity check preventing EEPROM dumps
> * Documentation additions
> * Fixed RxMode accepting untagged packets
> * Fixed ringparam allocation being too small
>
> v5:
> * Documentation changes
>
> v4:
> * Fixed assumption that master core always has id zero
> * Changed 1:1 core-to-port to 2 core (ethtool & ports) design
> * Included the correct documentation..
>
> v3:
> * Made use of enums for core state.
> * Fixed Makefile issue.
> * Fixed incorrect assumption with core ids.
> * Changed handling of more ports than cores.
>
> v2:
> * Replaced l2fwd base with simpler application.
> * Added ringparam functions.
> * Added documentation.

> Remy Horton (3):
> Remove ABI requirement for external library builds.
