Eric Dumazet 5933dd2f02 net: NET_SKB_PAD should depend on L1_CACHE_BYTES ... In old kernels, NET_SKB_PAD was defined to 16. Then commit d6301d3dd1 (net: Increase default NET_SKB_PAD to 32), and commit 18e8c134f4 (net: Increase NET_SKB_PAD to 64 bytes) increased it to 64. While first patch was governed by network stack needs, second was more driven by performance issues on current hardware. Real intent was to align data on a cache line boundary. So use max(32, L1_CACHE_BYTES) instead of 64, to be more generic. Remove microblaze and powerpc own NET_SKB_PAD definitions. Thanks to Alexander Duyck and David Miller for their comments.
