-Subject: [PATCH] bgmac: leave interrupts disabled as long as there is work
- to do
-
-Always poll rx and tx during NAPI poll instead of relying on the status
-of the first interrupt. This prevents bgmac_poll from leaving unfinished
-work around until the next IRQ.
-In my tests this makes bridging/routing throughput under heavy load more
-stable and ensures that no new IRQs arrive as long as bgmac_poll uses up
-the entire budget.
