`l2arc_mfuonly` was added to avoid wasting L2 ARC on read-once MRU data and metadata. However it can be useful to cache as much metadata as possible while, at the same time, restricting data cache to MFU buffers only. This patch allow for such behavior by setting `l2arc_mfuonly` to 2 (or higher). The list of possible values is the following: 0: cache both MRU and MFU for both data and metadata; 1: cache only MFU for both data and metadata; 2: cache both MRU and MFU for metadata, but only MFU for data.
