The tx interrupt is of edge type, and in case such interrupt is triggered while it is masked it will not be handled even after tx interrupts are re-enabled in the end of NAPI poll. This will cause tx network to stop in the following scenario: * Rx is being handled, hence interrupts are masked. * Tx interrupt is triggered after checking if there is some tx to handle and before re-enabling the interrupts. In this situation only rx transaction will release tx requests. In order to handle the tx that was missed( if there was one ), a NAPI reschdule was added after enabling the interrupts.
