Merge branch 'mlx5-updates'
Saeed Mahameed says:
====================
Mellanox 100G mlx5 updates 2016-11-29
The following series from Tariq and Roi, provides some critical fixes
and updates for the mlx5e driver.
From Tariq:
- Fix driver coherent memory huge allocation issues by fragmenting
completion queues, in a way that is transparent to the netdev driver by
providing a new buffer type "mlx5_frag_buf" with the same access API.
- Create UMR MKey per RQ to have better scalability.
From Roi:
- Some fixes for the encap-decap support and tc flower added lately to the
mlx5e driver.
v1->v2:
- Fix start index in error flow of mlx5_frag_buf_alloc_node, pointed out by Eric.
This series was generated against commit:
31ac1c19455f ("geneve: fix ip_hdr_len reserved for geneve6 tunnel.")
