[NET]: Allow skb headroom to be overridden
Previously we added NET_IP_ALIGN so an architecture can override the padding done to align headers. The next step is to allow the skb headroom to be overridden. We currently always reserve 16 bytes to grow into, meaning all DMAs start 16 bytes into a cacheline. On ppc64 we really want DMA writes to start on a cacheline boundary, so we increase that headroom to one cacheline. Signed-off-by: Anton Blanchard <anton@samba.org> Signed-off-by: David S.
