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. + */ + +#include "ice_lib.h" + +/** + * ice_aq_str - Convert an AdminQ error into a string + * @aq_err: the AQ error code to convert + * + * Convert the AdminQ status into its string name, if known.
