[PATCH 1/3] net: macb: reduce DEBUG output to make it more useful

[Michael Tretter]

The macb debugging output printed the function entry for various
functions. Especially for *_recv() this debugging flooded the serial
output while conveying very little information.

Remove printing of the function calls to make enabling debugging for the
macb driver more useful.
