Subject: [PATCH] ibmvnic: Use netdev_alloc_skb instead of alloc_skb to
replenish RX buffers
References: bsc#1184114 ltc#192237 bsc#1179243 ltc#189290
Patch-mainline: v5.11-rc1
Git-commit: e552aa313bbaf118b5f7b7f7fba7e28593f8d90d
Take advantage of the additional optimizations in netdev_alloc_skb when
allocating socket buffers to be used for packet reception.
