Merge branch 'net-generic-busy-polling'
Eric Dumazet says:
====================
net: extend busy polling support
This patch series extends busy polling range to tunnels devices,
and adds busy polling generic support to all NAPI drivers.
No need to provide ndo_busy_poll() method and extra synchronization
between ndo_busy_poll() and normal napi->poll() method.
This was proven very difficult and bug prone.
mlx5 driver is changed to support busy polling using this new method,
and a second mlx5 patch adds napi_complete_done() support and proper
SNMP accounting.
bnx2x and mlx4 drivers are converted to new infrastructure,
reducing kernel bloat and improving performance.
Latest patch, adding generic support, adds a new requirement :
-free_netdev() and netif_napi_del() must be called from process context.
Since this might not be the case in some drivers, we might have to
either : fix the non conformant drivers (by disabling busy polling on them)
or revert this last patch.
