ethtool: avoid signed-unsigned comparison in ethtool_validate_speed()
When building C++ userspace code that includes ethtool.h with "-Werror -Wall", g++ complains about signed-unsigned comparison in ethtool_validate_speed() due to definition of SPEED_UNKNOWN as -1. Explicitly cast SPEED_UNKNOWN to __u32 to match type of ethtool_validate_speed() argument. Signed-off-by: Michael Zhivich <mzhivich@akamai.com> Signed-off-by: David S. Miller <davem@davemloft.net>
