Horst Hartmann	dd30ac3274	[S390] net: provide architecture specific NET_SKB_PAD NET_SKB_PAD has been increased from 32 to 64 and later to max(32, L1_CACHE_BYTES). This led to a 25% throughput decrease for streaming workloads accompanied by a 37% CPU cost increase on s390. Define a architecture specific NET_SKB_PAD with the old value of 32.

[S390] net: provide architecture specific NET_SKB_PAD

NET_SKB_PAD has been increased from 32 to 64 and later to
max(32, L1_CACHE_BYTES). This led to a 25% throughput decrease for
streaming workloads accompanied by a 37% CPU cost increase on s390.
Define a architecture specific NET_SKB_PAD with the old value of 32.
