Uses logic from apps/fsutils/ipcfg to obtain the IP address configuration from a file, if available. This only effects the behavior of netinit if CONFIG_FSUTILS_IPCFG is selected and if an IP configuration file is available on a file system. Otherwise, it reverts to the preceding behavior.
Also adds definitions to apps/include/fsutils/ipcfg.h to formalize a bit encoding of the prototype which was already in use, but not documented.
Also fixes some bad assertions (duplication of PR #420) and makes use of variable names consistent in ipcfg.h comments and in ipcfg_text implementation.
This commit adds structures, modifies function prototypes, and renames data to support the future addition of IPv6 support. This commit does NOT add that IPv6, only the hooks for backward compatible future support.
This commit adds support to access an IPv4 Configuration file similar to the Linux dhpc.client ipfcg file. This version, tailored for deeply embedded systems supports several options to tailor the file and file access to different environments. It supports:
- Writable as well as read-only configuration files.
- ASCII human readable files as well as smaller binary files.
- It supports using character driver access to constrained media (such as EEPROM).
- Add examples/ipcfg to exercise IPv4 Configuration File support
