Hi Rengarajan,

This patch seems address two issues.
So I think it would be best to split it into two patches.

Also, are these problems bugs - do they have adverse effect visible by
users? If so perhaps they should be targeted at 'net' rather than
'net-next', and an appropriate Fixes tag should appear just above
the Signed-off-by line (no blank line in between).
