====================
Fix MODULE_DESCRIPTION() for net (p3)

There are hundreds of network modules that misses MODULE_DESCRIPTION(),
causing a warning when compiling with W=1. Example:

        WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/com90io.o
        WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/arc-rimi.o
        WARNING: modpost: missing MODULE_DESCRIPTION() in drivers/net/arcnet/com20020.o

This part3 of the patchset focus on the missing ethernet drivers, which
is now warning free. This also fixes net/pcs and ieee802154.
