Pyun YongHyeon fcb220acd1 Disable accepting frames in re_stop() to put RX MAC into idle state. ... Because there is no reliable way to know whether RX MAC is in stopped state, rejecting all frames would be the only way to minimize possible races. Otherwise it's possible to receive frames while stop command execution is in progress and controller can DMA the frame to freed RX buffer during that period. This was observed on recent PCIe controllers(i.e. RTL8111F). While this change may not be required on old controllers it wouldn't make negative effects on old controllers. One side effect of this change is disabling receive so driver reprograms RL_RXCFG to receive WOL frames when it is put into suspend or shutdown. This should address occasional 'memory modified free' errors seen on recent RealTek controllers.		2011-11-23 02:08:05 +00:00
