+Subject: [PATCH] rtl8xxxu: Enable aggregation for rtl8723au
+
+Implement rtl8xxxu_gen1_init_aggregation(). Aggregation should be the
+same for all gen1 parts. We may want to allow for tuning parameters in
+the fileopes struct. For now this is based allocating 16KB RX buffers,
+leaving 16000 bytes for actual packets, and the rest for the skb
+overhead.
