Alexander Duyck 2e7b872833 net: Do not allocate page fragments that are not skb aligned 
[ Upstream commit 3bed3cc4156eedf652b4df72bdb35d4f1a2a739d ]

This patch addresses the fact that there are drivers, specifically tun,
that will call into the network page fragment allocators with buffer sizes
that are not cache aligned. Doing this could result in data alignment
and DMA performance issues as these fragment pools are also shared with the
skb allocator and any other devices that will use napi_alloc_frags or
netdev_alloc_frags.

Fixes: ffde7328a3 ("net: Split netdev_alloc_frag into __alloc_page_frag and add __napi_alloc_frag")
