4.4-stable review patch. If anyone has any objections, please let me know.
------------------
From: Jack Morgenstein <ja...@dev.mellanox.co.il>
commit baa0be7026e2f7d1d40bfd45909044169e9e3c68 upstream.
The indentation in the QP1 GRH flow in procedure build_mlx_header is
really confusing. Fix it, in preparation for a commit which touches
this code.
Fixes: 1ffeb2eb8be9 ("IB/mlx4: SR-IOV IB context objects and proxy/tunnel SQP
support")
