| H A D | if_cpswreg.h | diff 246276 Sat Feb 02 23:12:13 MST 2013 kientzle Another overhaul of the CPSW driver for BeagleBone Major changes: * Finally tracked down the flow control setting that seems to have been causing TX stalls and watchdog timeouts * RX and TX paths now share a lot more code * TX interrupt is no longer used; we instead GC finished tx queue entries at the bottom of the start routine. * TX start now queues fragmented packets directly; it only invokes defrag() for occasional very fragmented packets. * "sysctl dev.cpsw" dumps controller statistics and queue counts * Host Error Interrupt will give extensive debugging information if the controller chokes on the queued data. |
