Subject: [PATCH net 2/9] net/smc: allow 16 byte pnetids in netlink policy

From: Hans Wippel <hwippel@...ux.ibm.com>

Currently, users can only send pnetids with a maximum length of 15 bytes
over the SMC netlink interface although the maximum pnetid length is 16
bytes. This patch changes the SMC netlink policy to accept 16 byte
pnetids.
