geneve: maximum value of VNI cannot be used
Geneve's Virtual Network Identifier (VNI) is 24 bit long, so the range of values for it would be from 0 to 16777215 (2^24 -1). However, one cannot create a geneve device with VNI set to 16777215. This patch fixes this issue. Signed-off-by: Girish Moodalbail <girish.moodalbail@oracle.com> Signed-off-by: David S. Miller <davem@davemloft.net>
