The QCA7000 firmware (or better: HomePlug Green PHY as such) does not provide rich possibilities for connection quality checks like other chipsets do. For example with QCA7500 it's possible to transfer some amount of data, then check the average data rate and use this value as connection quality indicator. As this is not possible with QCA7000, one possible indicator value could be the signal attenuation when both sides are SLAC capable.
This PR modifies the existings tools evse and pev to allow focusing on the sounding step only. In other words, it is possible to use the part of a complete SLAC session to determine the attenuation between two PLC peers without the overhead of changing NMK, waiting for QCA7000 reboots etc.
This is intended to be used e.g. in a test bed where this overhead is not desired or required.
And while documenting the new parameters, this PR also contains patches to bring the man pages back in sync with implementation.
