[PATCH v2 for-next 0/7] Add support for multicast loopback prevention to mlx4

2015-10-15 Thread Eran Ben Elisha 
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
layer is Ethernet. The new implementation is based on HW feature of dropping
incoming multicast packets if the sender QP counter index is equal to the
receiver counter index.

Patch 0001 extends ib_uverbs_create_qp in order to allow receiving the
multicast loopback flag at create flags.
Patch 0002 allows setting IB_QP_CREATE_BLOCK_MULTICAST_LOOPBACK in create_flag
field both from uverbs and ib_create_qp.
Patch 0003 adds an infrastructure for the counters' loopback prevention in the
mlx4_core.
Patch 0004 modifies mlx4_en QPs to use the new loopback prevention mode.
Patches 0005-0007 implements this feature for mlx4_ib driver.

Changes from v0:
Move loopback assignment outside the for loop according to Yuval's 
comment
rebase over to-be-rebased/for-4.3
Changes from v1:
rebase over k.o/for-4.4
Fix cover letter patch description - was out of order

Tested-by: Christoph Lameter 

Thanks,
Eran.

Doug,
I rebased the series due to a small conflict in
drivers/net/ethernet/mellanox/mlx4/fw.c

The git trees also need rebasing on github.com.
