Author: np Date: Tue Aug 18 19:04:55 2015 New Revision: 286897 URL: https://svnweb.freebsd.org/changeset/base/286897 Log: MFC r285648: cxgbe(4): Ask the firmware for the start of the RSS slice for a port and save it for later. This enables direct manipulation of the indirection tables (although the stock driver doesn't do that right now).
