Based on the original patch from Ying Cai <ycai@google.com> This change ensures that the itr/itr_setting adjustment logic is used, even for the default/compiled-in value. Context: When we changed the default InterruptThrottleRate value from default (3 = dynamic mode) to 8000 for example, only adapter->itr_setting (which controls interrupt coalescing mode) was set to 8000, but adapter->itr (which controls the value set in NIC register) was not updated accordingly. So from ethtool, it seemed the interrupt throttling is enabled at 8000 intr/s, but the NIC actually was running in dynamic mode which has lower CPU efficiency especially when throughput is not high.
