    Subject[PATCH 4.9 002/130] IB/rxe: Increase max number of completions to 32k
    Date
    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")
