Networking to storage is broken with "mlx4_en: Unknown parameter `num_lro'" after upgraded rhev-h to 6.2

Solution Unverified - Updated -

Issue

While using rhev-h 6.2, Mellanox network card does not come up and iSCSI storage connection is lost from hypervisor to iSCSI san. Dmesg shows below error,

mlx4_en: Unknown parameter `num_lro'

Manually trying to load the module after the hypervisor is booted also fails with the below error.

# modprobe mlx4_en
FATAL: Error inserting mlx4_en (/lib/modules/2.6.32-220.17.1.el6.x86_64/kernel/drivers/net/mlx4/mlx4_en.ko): Unknown symbol in module, or unknown parameter (see dmesg)
