Subject: [PATCH net-next 4/6] doc, net: Update netdev operation names

Commits d314774cf2cd5dfeb39a00d37deee65d4c627927 ('netdev: network
device operations infrastructure') and
008298231abbeb91bc7be9e8b078607b816d1a4a ('netdev: add more functions
to netdevice ops') moved and renamed net device operation pointers.
