eth: add missing xdp.h includes in drivers Handful of drivers currently expect to get xdp.h by virtue of including netdevice.h. This will soon no longer be the case so add explicit includes.

net: Remove the obsolte u64_stats_fetch_*_irq() users (drivers). Now that the 32bit UP oddity is gone and 32bit uses always a sequence count, there is no need for the fetch_irq() variants anymore. Convert to the regular interface.

net: Use u64_stats_fetch_begin_irq() for stats fetch. On 32bit-UP u64_stats_fetch_begin() disables only preemption. If the reader is in preemptible context and the writer side (u64_stats_update_begin*()) runs in an interrupt context (IRQ or softirq) then the writer can update the stats during the read operation. This update remains undetected. Use u64_stats_fetch_begin_irq() to ensure the stats fetch on 32bit-UP are not interrupted by a writer. 32bit-SMP remains unaffected by this change. Cc: "David S.

net/funeth: Support UDP segmentation offload Handle skbs with SKB_GSO_UDP_L4, advertise the offload in features, and add an ethtool counter for it. Small change to existing TSO code due to UDP's different header length.

net/funeth: Fix fun_xdp_tx() and XDP packet reclaim The current implementation of fun_xdp_tx(), used for XPD_TX, is incorrect in that it takes an address/length pair and later releases it with page_frag_free(). It is OK for XDP_TX but the same code is used by ndo_xdp_xmit. In that case it loses the XDP memory type and releases the packet incorrectly for some of the types. Assorted breakage follows. Change fun_xdp_tx() to take xdp_frame and rely on xdp_return_frame() in reclaim.

net/fungible: Fix local_memory_node error Stephen Rothwell reported the following failure on powerpc: ERROR: modpost: ".local_memory_node" [drivers/net/ethernet/fungible/funeth/funeth.ko] undefined! AFAICS this is because local_memory_node() is a non-inline non-exported function when CONFIG_HAVE_MEMORYLESS_NODES=y. It is also the wrong API to get a CPU's memory node. Use cpu_to_mem() in the two spots it's used.
