What does this PR do?

This PR was previously applied in #11056
However, this triggered segfault as the buffer's size was incorrect as _u32 element was only counted as one byte.

1 + 32 + 32 + 32 + 32 + 32 + 12 + 5
178

While the correct size should have been

4 + 32 + 32 + 32 + 32 + 32 + 12 + 5 * 4
196

A sizeof confirms it

#include <linux/ethtool.h>
#include <stdio.h>

int main (int argc, char *argv[])
{
    printf("%zu\n", sizeof(struct ethtool_drvinfo));
    return 0;
}

gcc test.c && ./a.out 
196

Motivation

This will provide per queue stats.
