Author: landonf Date: Thu Dec 14 01:58:05 2017 New Revision: 326836 URL: https://svnweb.freebsd.org/changeset/base/326836 Log: bhnd(4): Include board_devid in the bhnd_board_info structure, and populate the expected default board_vendor value on MIPS SoCs. This is required by bwn(4) to differentiate between single-band and dual-band device variants that otherwise share a common chip ID.
