|
|
* SPECIFICATION: ........
|
|
*
|
|
* DESC : generic functions to handle the download of NIC firmware
|
|
* Local Support Routines for above procedures
|
|
*
|
|
* Customizable via HCFCFG.H, which is included by HCF.H
|
|
*
|
|
*
|
|
* DHF is (intended to be) platform-independent.
|
|
* DHF is a module that provides a number of routines to download firmware
|
|
* images (the names primary, station, access point, secondary and tertiary
|
|
* are used or have been used) to volatile or nonvolatile memory
|
|
* in WaveLAN/IEEE NICs. To achieve this DHF makes use of the WaveLAN/IEEE
|
|
* WCI as implemented by the HCF-module.
|
|
*
|
|
* Download to non-volatile memory is used to update a WaveLAN/IEEE NIC to new
|
|
* firmware. Normally this will be an upgrade to newer firmware, although
|
|
* downgrading to older firmware is possible too.
|
|
*
|
|
* Note: relative to Asserts, the following can be observed:
|
|
* Since the IFB is not known inside the routine, the macro HCFASSERT is replaced with MMDASSERT.
|
|
* Also the line number reported in the assert is raised by FILE_NAME_OFFSET (10000) to discriminate the
|
|
* DHF Asserts from HCF and MMD asserts.
