6.6-stable review patch. If anyone has any objections, please let me know. ------------------ From: Andy Chiu <andy.chiu@xxxxxxxxxx> [ Upstream commit 799a829507506924add8a7620493adc1c3cfda30 ] softirq may get lost if an Rx interrupt comes before we call napi_enable. Move napi_enable in front of axienet_setoptions(), which turns on the device, to address the issue.
