ethtool.h compile warning on c++

I am getting warnings about sign missmatch.

Maybe make SPEED_UNKNOWN be ((__u32)(0xFFFFFFFF)) ?

from ethtool.h:

#define SPEED_UNKNOWN           -1

static inline int ethtool_validate_speed(__u32 speed)
{
         return speed <= INT_MAX || speed == SPEED_UNKNOWN;
}

Thanks,
Ben

The 0xFFFFFFFFU could be better.
