[dpdk-dev,3/5] examples/netmap: fix overflow in ioctl operation
Commit Message
Compiling the netmap example with clang-3.5 triggered the following
warning:
compat_netmap.c:783:11: error: overflow converting case value to
switch condition type (3225184658 to 18446744072639768978)
[-Werror,-Wswitch]
case NIOCREGIF:
^
Indeed, an ioctl value should be an unsigned 32 bits, not an int.
