Min Hu (Connor) April 28, 2021, 8:42 a.m. UTC 
From: Huisong Li <lihuisong@huawei.com>

Currently, the pause command in ethtool to enable Rx/Tx pause has the
following problem. Namely, Assume that the device supports flow control
auto-negotiation to set pause parameters, which will the device that does
not support flow control auto-negotiation fails to run this command.

This patch supports the configuration of flow control auto-negotiation
and fixes the print format and style of the pause cmd to make it more
readable.

Fixes: bda68ab9d1e7 ("examples/ethtool: add user-space ethtool sample application")
