DIV_ROUND_UP is defined in linux/kernel.h only for the kernel.
When ethtool.h is included by a userland app, we got the following error:
include/linux/ethtool.h:1218:8: error: variably modified 'queue_mask' at file scope
__u32 queue_mask[DIV_ROUND_UP(MAX_NUM_QUEUE, 32)];
^
Let's add a common definition in uapi and use it everywhere.
Fixes: ac2c7ad0e5 ("net/ethtool: introduce a new ioctl for per queue setting")
