Subject: [PATCH v2 net-next 0/4] net: extend alloc_skb_with_frags() max size

alloc_skb_with_frags(), while being able to use high order allocations,
limits the payload size to PAGE_SIZE * MAX_SKB_FRAGS

Reviewing Tahsin Erdogan patch [1], it was clear to me we need
to remove this limitation.

v2: Addressed Willem feedback on 1st patch.

  net: allow alloc_skb_with_frags() to allocate bigger packets
  net: tun: change tun_alloc_skb() to allow bigger paged allocations
  net/packet: change packet_alloc_skb() to allow bigger paged
    allocations
  net: tap: change tap_alloc_skb() to allow bigger paged allocations
