2013-03-10cns3xxx: fix an rx irq handling corner casenbd
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

2012-12-04cns3xxx: fix dwc_otg driver compat with udc-coreflorian
function. This removes those from the dwc_otg driver and removes the patch that comments out the linkage of udc-core so that the dwc_otg driver can co-exist happily with other USB Device Controllers.
