Hello,
when checking users of get_user_pages() (I'm doing some cleanups in that
area to fix filesystem's issues with mmap_sem locking) I've noticed that
infiniband drivers add number of pages obtained from get_user_pages() to
mm->pinned_vm counter. Although this makes some sence, it doesn't ma

The RDMA stack allows for applications to create IB_QPT_RAW_PACKET QPs,

Re-arrange some of code which fills DMFS HW structures so we can use it from
within the core driver and from the IB driver too, e.g when verbs DMFS

Also, add struct mlx4_flow_handle struct which will be of use by the DMF

Hi Roland, all
The first five patches in the series are mlx4 DMFS (Device Managed Flow

Change struct mlx4_net_trans_rule_hw_eth :: vlan_id name to vlan_tag
Change struct mlx4_net_trans_rule_hw_ib :: r_u_qpn name to l3_qpn
The patch doesn't introduce any functional change or API change
towards the firmware.
