/**
* @file ice_strings.c
* @brief functions to convert enumerated values to human readable strings
*
* Contains various functions which convert enumerated values into human
* readable strings. Primarily this is used for error values, such as the
* ice_status enum, the ice_aq_err values, or standard sys/errno.h values.
*
* Additionally, various other driver enumerations which are displayed via
* sysctl have converter functions.
*
* Some of the functions return struct ice_str_buf, instead of a character
* string pointer. This is a trick to allow the function to create a struct
* with space to convert unknown numeric values into a string, and return the
* contents via copying the struct memory back. The functions then have an
* associated macro to access the string value immediately. This allows the
* functions to return static strings for known values, and convert unknown
* values into a numeric representation. It also does not require
* pre-allocating storage at each callsite, or using a local static value
* which wouldn't be re-entrant, and could collide if multiple threads call
* the function. The extra copies are somewhat annoying, but generally the
* error functions aren't expected to be in a hot path so this is an
* acceptable trade off.
