If we want to add proper XRC support it should be done with a new
struct ib_xrc_wr.
This shrinks the various WR structures by another 4 bytes.

- patch 2 now explicitly replaces the weird overloading in the mlx5
driver with an explicit embedding of struct ib_send_wr, similar
to what we do for all other MRs.
This is on the user-space memory registration path.
Haggai, can you grab it for a Tested-by tag?

Hi Doug,
This patch-set adds a new implementation for multicast loopback prevention for
mlx4 driver. The current implementation is very limited, especially if link

A mlx5 Ethernet port must be explicitly enabled for RoCE.
When RoCE is not enabled on the port, the NIC will refuse to create
QPs attached to it and incoming RoCE packets will be considered by the
NIC as plain Ethernet packets.

Hi Doug,
This patchset adds RoCE V1 and RoCE V2 support to the mlx5 device
driver.
This patchset was applied and tested over patchset Add RoCE v2
support which was sent to the mailing list by Matan Barak.
Achiad Shochat (10):
IB/mlx5: Support IB device's callback for getting the link layer
Introduce a new function called mlx5_query_nic_vport_context().
This function gets all the NIC vport attributes from the device.
The MAC address is just one of the NIC vport attributes, so
mlx5_query_nic_vport_mac_address() is now just a wrapper function
above mlx5_query_nic_vport_context().
These callbacks write into the mlx5 RoCE address table.
Upon del_gid we write a zero'd GID.

Make the existing mlx5_ib_port_link_layer() signature match
the ib device callback signature (add port_num parameter).
Refactor it to use a sub function so that the link layer could
be queried also before the ibdev is created.
