l2: fix array-bounds error for prefetch on Arm
make build-release CC=gcc-10
vpp/src/vppinfra/cache.h:73:31: error: array subscript 80 is outside
array bounds of ‘l2_in_out_feat_arc_main_t[1]’ [-Werror=array-bounds]
__builtin_prefetch (_addr + (n) *CLIB_CACHE_PREFETCH_BYTES,
_CLIB_PREFETCH (3, size, type);
vpp/src/vnet/l2/l2_in_out_feat_arc.c:260:3:
note: in expansion of macro ‘CLIB_PREFETCH’
CLIB_PREFETCH (next_node_indices, 2 * CLIB_CACHE_LINE_BYTES, LOAD);
2 * CLIB_CACHE_LINE_BYTES is 256 bytes on Arm, the offset is out of range of
fam->feat_next_node_index[1], which is 128 bytes, use sizeof array instead.
Type: fix
