* cns3xxx: fix an rx irq handling corner caseFelix Fietkau2013-03-101-5/+5
| | | | | | | | | | | | | | | | When an rx interrupt comes in, rx interrupts are disabled and NAPI polling is scheduled. During the NAPI poll, the driver first processes received frames in the ring, then fills the dma descriptor slots with new buffers and calls tx complete, before finally re-enabling rx interrupts and completing NAPI (if below the budget). If the hardware rx queue overflows before the napi complete is called, the hardware will not throw any further rx interrupts and rx processing stops completely. Fix this by keeping NAPI polling scheduled until it completes a poll without receiving any packets, and also handle NAPI completion before refilling rx or completing tx. git-svn-id: svn://svn.openwrt.org/openwrt/trunk@35942 3c298f89-4303-0410-b956-a3cf2f4a3e73

* [cns3xxx]: add nol2x0 cmdline to disable l2x0 cacheImre Kaloz2012-12-231-2/+0
| | | | | | | | | | | | L2 cache via L2X0 cache controller available on some ARM boards can provide a performance boost in some situations but decrease performance in others. This adds a kernel cmdline to disable L2X0 for cns3xxx based boards.
