Author: arybchik Date: Sat Nov 24 18:13:21 2018 New Revision: 340907 URL: https://svnweb.freebsd.org/changeset/base/340907 Log: sfxge(4): add function to create packed stream RxQ Encoding packed stream buffer size in RxQ type is not a future-proof idea taking into account a new RxQ types with extra parameters. To be consistent make packet stream buffer size a separate parameter. In order to avoid blowing of the default RxQ create function prototype add a dedicated function to create packed stream RxQ without not applicable paramters.
