Jesper Dangaard Brouer f842b9cfa0 ixgbe: Fix XDP redirect on archs with PAGE_SIZE above 4K
[ Upstream commit 88eb0ee17b2ece64fcf6689a4557a5c2e7a89c4b ]

The ixgbe driver have another memory model when compiled on archs with
PAGE_SIZE above 4096 bytes. In this mode it doesn't split the page in
two halves, but instead increment rx_buffer->page_offset by truesize of
packet (which include headroom and tailroom for skb_shared_info).

This is done correctly in ixgbe_build_skb(), but in ixgbe_rx_buffer_flip
which is currently only called on XDP_TX and XDP_REDIRECT, it forgets
to add the tailroom for skb_shared_info. This breaks XDP_REDIRECT, for
veth and cpumap.  Fix by adding size of skb_shared_info tailroom.

Maintainers notice: This fix have been queued to Jeff.
