Value must be a power of 2 due to HW limitation.
Driver supports only 'equal' mode in ethtool and can't be set by using weights.

Subject: mlx4_core: Fix mtt profile issue

Num mtts from profile is really the number of mtt segments.
Thus, in make profile, to get the proper number of MTT entries,
must multiply num_mtts by mtts per segment.

Slave async events were mapped to single eq. This patch fixes this issue, so
the slaves can map the async events to any eq.
