#!/bin/bash
# This program, that should only be used by the manufacturer,
# creates and SDB image file, to be written in dataflash:
# (/dev/mtd5 in the switch).
#
# 0x000000094800-0x000000095040 : "hwinfo"
#
# The sdb file has a predefined structure, and we are not expected to
# change the manufacturer name. We chose to have it "hardwired", in a
# way, to avoid building gensdbfs during switch installation, as it's
# an extra burden and an extra dependency. We rather use sed for mac
# addresses (like we always did) and we write hwinfo in place, at
# offset 0x420.
# See hwinfo-sdb/--SDB-CONFIG-- and the respective
# commit for details.
