History
Andriy Gapon 4c3b02bfce reduce L2ARC_WRITE_SIZE on FreeBSD 
FreeBSD has ARC_BUFC_NUMMETADATALISTS metadata lists and ARC_BUFC_NUMDATALISTS
data lists (currently both are 16) while illumos has just a single list
of each kind.

L2ARC_WRITE_SIZE determines the default value of l2arc_write_max which
defines limits on how much data is scanned and written to a cache device
during each run of the l2arc feed thread.  The limits are applied on the
per buffer list basis.
Because FreeBSD has more lists we proportionally reduce the limits.
