If support-multi-driver option been set, we suppose the DPDK will
not modify the value of global register GLQF_FD_MSK. Current
situation is if we create a new flow with 'flow creat ...' command,
the register value may be changed.

Thanks for the fix, the patch looks OK for me, but the commit log should be amended.
How about
"If support-multi-driver is enabled, the global registers should not be configured.
But with the correct code base, if creating a flow with rte_flow API, the global
register GLQF_FD_MSK may be changed." ?

Could you mention multi-driver in the err log? otherwise this info is misleading.
