From: Moiz Sonasath <[email protected]> There seems to be a bug in the ioctl implementation in /kernel/net/core/dev.c dev_ifsioc_locked() case SIOCGIFMAP: ifr->ifr_map.irq = dev->irq; // ?? type mismatch
Here ifr->ifr_map.irq) is of type unsigned char dev-irq is of type unsigned int So ifconfig reports a wrong irq number when the dev->irq number is > 255. I am confused to see the same typedefs in file: net/if.h Not sure how to make changes for the user side net/if.h file?
