* env: Add a command to display details about env flagsJoe Hershberger2012-12-13-0/+11
| | | | | | | Similar to the env callback command, this will show details about the options available, the static list, and the currently active variables. Signed-off-by: Joe Hershberger <joe.hershberger@ni.com>
* tools/env: Add environment variable flags supportJoe Hershberger2012-12-13-0/+19
| | | | | | | | | | | | | | Currently just validates variable types as decimal, hexidecimal, boolean, ip address, and mac address. Call env_acl_validate_setenv_params() from setenv() in fw_env.c. If the entry is not found in the env .flags, then look in the static one. This allows the env to override the static definitions, but prevents the need to have every definition in the environment distracting you. Need to build in _ctype for isdigit for Linux.
