Hi Dave,
This series from Tariq includes micro data path optimization for mlx5e
netdevice driver.
Sorry about the late submission but most of the patches are really
small and trivial.
For more details please see tag log message below.
Please pull and let me know if there's any problem.
Thanks,
Saeed.

net/mlx5e: Distribute RSS table among all RX rings (2017-09-03 06:34:09 +0300)
----------------------------------------------------------------
mlx5-updates-2017-09-03
This series from Tariq includes micro data path optimization for mlx5e
netdevice driver.
Mainly Tariq introduces the following changes to NAPI and RX handling
path of the driver:
- RX ring structure reorganizing
- Trivial code refactoring and optimization
- NAPI busy-poll for when fast UMR is in progress
- Non-atomic state operations in NAPI context
- Remove unnecessary fields from fast path structures
- page-cache micro optimization
- Rely on NAPI to avoid missing an IRQ for RX/TX shared NAPI contexts
- Stop NAPI when irq changes affinity
- Distribute RSS table among all RX rings
Thanks,
Saeed.
