Subject: mlx4_core: Increase max number of QPs per multicast group to 56
X-Git-Tag: v2.6.24-rc1~1453^2~33

mlx4_core: Increase max number of QPs per multicast group to 56

Increase the number of QPs allowed per multicast group from 8 to 56.
This allows for one QP per core on 16-core systems, which are now
quite common, and allows some space for future growth.
