Subject: [PATCH net-next 0/3] net: better packing of global vars

From: Eric Dumazet <edumazet@...gle.com>

First two patches avoid holes in data section,
and last patch makes sure some siphash keys are contained
in a single cache line.

Eric Dumazet (3):
  once: use __section(".data.once")
  net: use .data.once section in netdev_level_once()
  net: align static siphash keys
