+Subject: [PATCH 16/16] nss-dp: use proper netdev MAC helpers
+
+mac_addr is const, so utilize proper helpers for setting random and
+desired MAC addres as old ones were dropped in newer kernels.

+Subject: [PATCH] nss-dp: adapt to netif_napi_add() changes
+
+netif_napi_add() removed the weight argument and just uses the default
+NAPI_POLL_WEIGHT in background, so for those requiring custom weight use
+netif_napi_add_weight() instead.
