Sorry, I still don't understand the bug you are fixing. It shouldn't
take more than one minute to understand a commit log.
I prose that you rewrite the commit log, or at least parts of if it.
When you are describing a bug don't talk about enums or source files,
that's an implementation detail, and instead talk how the bug looks like
from users point of view. For example:
"On HP laptop model 1234 with Realtex 4321 device users are supposed
to use ant_sel module parameter with value 77 to use the correct
antenna. But instead rtlwifi incorrectly chose antenna 88 with lower
transmit power and that caused packet loss. Fix it so that the user
gets better transmit power and..."
(that's of course all made up information as I don't know what the
actual bug is)
And after that you can write rtlwifi internals in the commit log as much
as you want :) But there needs to be a clear generic description of the
bug first and it needs to understandable in one read.
To make this faster I propose that you send the new commit log as a
reply to this mail and I can then comment faster.
