INT_MAX needs limits.h in userland.
When ethtool.h is included by a userland app, we got the following error:
.../usr/include/linux/ethtool.h: In function 'ethtool_validate_speed':
.../usr/include/linux/ethtool.h:1471:18: error: 'INT_MAX' undeclared (first use
in this function)
return speed <= INT_MAX || speed == SPEED_UNKNOWN
^
Fixes: e02564ee334a ("ethtool: make validate_speed accept all speeds between 0
and INT_MAX")
