Subject: net/mlx4_core: VFs must ignore the enable_64b_cqe_eqe module param
From: Jack Morgenstein <jackm@xxxxxxxxxxxxxxxxxx>
[ Upstream commit b30513202c6c14120f70b2e9aa1e97d47bbc2313 ]
Slaves get the 64B CQE/EQE state from QUERY_HCA, not from the module parameter.
If the parameter is set to zero, the slave outputs an incorrect/irrelevant
warning message that 64B CQEs/EQEs are supported but not enabled (even if the
hypervisor has enabled 64B CQEs/EQEs).
