Subject: remove array_size duplicates
From: Roel Kluin <12o3l@xxxxxxxxxx>
Remove some ARRAY_SIZE macro duplicates. There is also one in
arch/um/include/user.h, which isn't fixed here because comments in that
file explicitly state a preference for the 'less fancy' version. If that's
the case as well for any of the other replacements please comment.
Several #defines in net drivers were found to be unused and are simply deleted.
