Bill Paul 55ad415824 When ndis_attach() runs, it has to very briefly initialize the card ... in order to query the underlying Windows driver for the station address and some other properties. There is a slim chance that the card may receive a packet and indicate it up to us before ndis_attach() can call ndis_halt_nic(). This is bad, because both the softc structure and the ifnet structure aren't fully initialized yet: many pointers are still NULL, so if we make it into ndis_rxeof(), we will panic. To fix this, we need to do the following: - Move the calls to IoAllocateWorkItem() to before the call to ndis_init_nic(). - Move the initialization of the RX DPC and status callback function pointers to before ndis_init_nic() as well. - Modify ndis_rxeof() to check if the IFF_DRV_RUNNING flag is set. If it isn't, we return any supplied NDIS_PACKETs to the NIC without processing them. This fixes a crash than can occur when activating a wireless NIC in close proximity to a very busy wireless network, reported by Ryan Beasley (ryan%^$!ATgoddamnbastard-****!!!DOTorg.
