Subject: igb: warn if max_vfs limit is exceeded
X-Git-Tag: firefly_0821_release~7613^2~2196^2~170^2~23

igb: warn if max_vfs limit is exceeded

Currently there's no warning printed when max_vfs > 7 is specified with
igb and the maximum of 7 is silently enforced. This patch prints a
warning and informs the user of the actions taken.
