Subject: [PATCH] Adding a workaround for enabling steering in ConnectX-3
 devices

This file will add this configuration
"options mlx4_core log_num_mgm_entry_size=-1" to
/etc/modprobe.d/mlx4.conf file in order to enable steering in
ConnectX-3 devices and then will rebuild the initramfs at the first
boot stage
