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.
