4.9-stable review patch.  If anyone has any objections, please let me know.

------------------

From: Yonatan Cohen <yonatanc@mellanox.com>

commit d680ebed91e0b45c43ae03a880a0b43211096161 upstream.

Increase limit of max CQE from 8K to 32K to allow demanding
applications to work over SoftRoCE with same configuration
as most RoCEv2 HW vendors have.

Fixes: 8700e3e7c485 ("Soft RoCE driver")
