powerpc: optimise csum_partial() call when len is constant csum_partial is often called for small fixed length packets for which it is suboptimal to use the generic csum_partial() function. For instance, in my configuration, I got: * One place calling it with constant len 4 * Seven places calling it with constant len 8 * Three places calling it with constant len 14 * One place calling it with constant len 20 * One place calling it with constant len 24 * One place calling it with constant len 32 This patch renames csum_partial() to __csum_partial() and implements csum_partial() as a wrapper inline function which * uses csum_add() for small 16bits multiple constant length * uses ip_fast_csum() for other 32bits multiple constant * uses __csum_partial() in all other cases Signed-off-by: Christophe Leroy <christophe.leroy@c-s.fr> Signed-off-by: Scott Wood <oss@buserror.net>
