Merge branch 'net-napi-addition-of-napi_defer_hard_irqs'
Eric Dumazet says:
====================
net: napi: addition of napi_defer_hard_irqs
This patch series augments gro_glush_timeout feature with napi_defer_hard_irqs
As extensively described in first patch changelog, this can suppresss
the chit-chat traffic between NIC and host to signal interrupts and re-arming
them, since this can be an issue on high speed NIC with many queues.
The last patch in this series converts mlx4 TX completion to
napi_complete_done(), to enable this new mechanism.
