nit: actually not sure why we need the define on the left, since the
usage could just use the ones its sourced from on the right.

alan: as per offline conversation, we beilieve the default size needs t
to larger to accomodate back to back worst case capture sizes.
So as per offline, we need to increase that to at least 32K? (or 128K
with spare)
