Hi,
I'm having some problems registering a network device on Android. The
code works well on linux but on Android I'm getting a kernel panic
when I execute 'result = register_netdev(Adapter->dev);' (code and
error below).
Any guidance on what might be wrong greatly appreciated.
Chris
int register_networkdev(PMINI_ADAPTER Adapter)
{
int result=0;
Adapter->dev = alloc_etherdev(sizeof(PMINI_ADAPTER));
if(!Adapter->dev)
{
BCM_DBG_PRINT(BCM_ERR, "ERR: No Dev");
return -ENOMEM;
}
gblpnetdev =
Adapter->dev;
ether_setup(Adapter->dev);
Adapter->dev->open = bcm_open;
Adapter->dev->mtu =
1400;//MTU_SIZE; /* 1400 Bytes */
Adapter->dev->stop = bcm_close;
Adapter->dev->get_stats = bcm_get_stats;
Adapter->dev->hard_start_xmit = bcm_transmit;
/* Read the MAC Address from EEPROM */
ReadMacAddressFromEEPROM(Adapter);
DBG_PRINT(SCREAM, "1\n");
/* Register the notifier block for getting netdevice events */
DBG_PRINT(SCREAM, "Registering netdevice notifier\n");
result = register_netdevice_notifier(&bcm_notifier_block);
DBG_PRINT(SCREAM, "2\n");
if(result)
{
DBG_PRINT(SCREAM, "Notifier Block did not get registered");
Adapter->bNetdeviceNotifierRegistered = FALSE;
return result;
}
else
{
DBG_PRINT(SCREAM, "Notifier got Registered");
Adapter->bNetdeviceNotifierRegistered = TRUE;
}
result = register_netdev(Adapter->dev);
DBG_PRINT(SCREAM, "3\n")
if (!result)
{
Adapter->bNetworkInterfaceRegistered = TRUE ;
DBG_PRINT(SCREAM, "Network device name is %s!", Adapter->dev-
>name);
}
else
{
DBG_PRINT(SCREAM, "Network device can not be registered!");
Adapter->bNetworkInterfaceRegistered = FALSE ;
return result;
}
DBG_PRINT(SCREAM, "4\n")
return 0;
}
