kernel: pick patches for MediaTek Ethernet from linux-next

Pick patches with several fixes and improvements, preparation for upcoming WED (TX) [1] as well as basic XDP support [2] with MediaTek's Filogic SoCs to the mtk_eth_soc driver. Also pick follow-up patch fixing Ethernet on MT7621 [3]. Tested on Bananapi BPi-R3 (MT7986), Bananapi BPi-R64 (MT7622), Bananapi BPi-R2 (MT7623), MikroTik RouterBoard M11G (MT7621). [1]: https://patchwork.kernel.org/project/netdevbpf/list/?series=662108&state=* [2]: https://patchwork.kernel.org/project/netdevbpf/list/?series=675368&state=* (the first part of the series adding wed nodes to mt7986a.dtsi was applied to the copy of mt7986a.dtsi in our tree) [3]: https://git.kernel.org/pub/scm/linux/kernel/git/netdev/net.git/commit/?id=5e69163d3b9931098922b3fc2f8e786af8c1f37e Signed-off-by: Daniel Golle <daniel@makrotopia.org>

+
+    page_pool: Add allocation stats
+    
+    Add per-pool statistics counters for the allocation path of a page pool.
+    These stats are incremented in softirq context, so no locking or per-cpu
+    variables are needed.
+    
+    This code is disabled by default and a kernel config option is provided for
+    users who wish to enable them.
+    
+    The statistics added are:
+            - fast: successful fast path allocations
+            - slow: slow path order-0 allocations
+            - slow_high_order: slow path high order allocations
+            - empty: ptr ring is empty, so a slow path allocation was forced.
+            - refill: an allocation which triggered a refill of the cache
+            - waive: pages obtained from the ptr ring that cannot be added to
+              the cache due to a NUMA mismatch.

+    xdp: introduce flags field in xdp_buff/xdp_frame
+    
+    Introduce flags field in xdp_frame and xdp_buffer data structures
+    to define additional buffer features. At the moment the only
+    supported buffer feature is frags bit (XDP_FLAGS_HAS_FRAGS).
+    frags bit is used to specify if this is a linear buffer
+    (XDP_FLAGS_HAS_FRAGS not set) or a frags frame (XDP_FLAGS_HAS_FRAGS
+    set). In the latter case the driver is expected to initialize the
+    skb_shared_info structure at the end of the first buffer to link together
+    subsequent buffers belonging to the same frame.

+MIME-Version: 1.0

+
+Disable page_pool/XDP support for MT7621 SoC in order fix a regression
+introduce adding XDP for MT7986 SoC. There is no a real use case for XDP
+on MT7621 since it is a low-end cpu. Moreover this patch reduces the
+memory footprint.
