common/env_flags.c: Add function to validate a MAC address

2015-09-21T15:29:47+00:00

The code that checks if a string has the format of a MAC address has been
moved to a separate function called eth_validate_ethaddr_str().

This has been done to allow other components (such as vsc9953 driver)
to validate a MAC address.

env: Allow env_attr_walk to pass a priv * to callback

2015-05-21T13:13:19+00:00

In some cases it can be helpful to have context in the callback about
the calling situation. This is needed for following patches.

common, env: optimize boottime

2014-01-14T14:01:06+00:00

when creating the hashtable, for each environmentvariable
getenv(ENV_CALLBACK_VAR) and getenv(ENV_FLAGS_VAR) is called,
which costs at this point a lot of time. So call this two
getenv() calls only once.

Boottime on the ids8313 board without this patch:

2013-12-19 13:38:27,659:  In:    serial

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

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.
