But, in the process it did not update the enabled_tc value that it caches on a per VEB basis. So, when the next reconfiguration event occurs where the number of TC value is same as the value cached in enabled_tc for a given VEB; driver does not modify it's TC configuration by calling appropriate AQ command believing it is running with the same configuration as requested. Now, as the VEB is not actually enabled for the TCs that are there any TC configuration command for VSI attached to that VEB with TCs that are not enabled for the VEB fails. This patch fixes this issue.
