The global variable n_krcvqs stores the sum of the number of kernel receive queues of VLs 0-7 which the user can pass to the driver through the module parameter array krcvqs which is of type unsigned integer. If the user passes large value(s) into krcvqs parameter array, it can cause an arithmetic overflow while calculating n_krcvqs which is also of type unsigned int. The overflow results in an incorrect value of n_krcvqs which can lead to kernel crash while loading the driver. Fix by changing the data type of n_krcvqs to unsigned long. This patch also changes the data type of other variables that get their values from n_krcvqs.
