+Subject: [PATCH] ethtool: extend coalesce setting uAPI with CQE mode
+
+In order to support more coalesce parameters through netlink,
+add two new parameter kernel_coal and extack for .set_coalesce
+and .get_coalesce, then some extra info can return to user with
+the netlink API.

+Subject: i40e: Fix ATR queue selection
+
+Without this patch, ATR does not work. Receive/transmit uses queue
+selection based on SW DCB hashing method. 
+
+If traffic classes are not configured for PF, then use
+netdev_pick_tx function for selecting queue for packet transmission.
+Instead of calling i40e_swdcb_skb_tx_hash, call netdev_pick_tx,
+which ensures that packet is transmitted/received from CPU that is 
+running the application.
+
+Reproduction steps:
+1. Load i40e driver
+2. Map each MSI interrupt of i40e port for each CPU
+3. Disable ntuple, enable ATR i.e.:
+ethtool -K $interface ntuple off
+ethtool --set-priv-flags $interface flow-director-atr
+4. Run application that is generating traffic and is bound to a
+single CPU, i.e.:
+taskset -c 9 netperf -H 1.1.1.1 -t TCP_RR -l 10
+5. Observe behavior:
+Application's traffic should be restricted to the CPU provided in
+taskset.
