Yes.  Lower is always safer, but may degrade performance.

The problem is that the default value is global for all ports and
NIC:s, and it would probably not be appreciated by people who has
hardware that copes with the 32k buffer if we change it globally.  The
right way to solve this is probably to make the default buffer size
into a kernel parameter.
