Use the variable access flags to implement the protection for ethaddr
and serial# instead of hard-coding them.

env: Add a command to display details about env flags

Similar to the env callback command, this will show details about the
options available, the static list, and the currently active variables.

tools/env: Add environment variable flags support

2012-12-13T18:46:56+00:00

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.
