I'll expand the names.
Regarding MseA/B/C/D, I'll admit I am also a bit fuzzy about them.
They describe link-quality settings, and the values have some meaning to the
chip guys [when I talked witht them about
it], but I did not insist on getting a deep explanation about them [and what
their values represent].
I guess for this PHY driver, we could drop them, and if they're needed they can
be accessed via phytool, and if they're
really needed, I can try to add them later with more complete detail [about
them and their use/value].
I included them here, because they are listed in the error-counter register
"group" [in the datasheet], and I inertially
added them.
