Sometimes, it will cause sending performance lower than expected. To fix this bug, we set tx ring interrupts packets line to 1 forever, to avoid count clear. And set the gap time to 20us, to solve the problem that too many interrupts engendered when packets line is 1. This patch could advance the send performance on ARM from 6.6G to 9.37G when an iperf send thread on ARM and an iperf send thread on X86 for XGE.
