netlink: specs: mptcp: fix port endianness
The MPTCP port attribute is in host endianness, but was documented
as big-endian in the ynl specification.
Below are two examples from net/mptcp/pm_netlink.c showing that the
attribute is converted to/from host endianness for use with netlink.
Import from netlink:
addr->port = htons(nla_get_u16(tb[MPTCP_PM_ADDR_ATTR_PORT]))
Export to netlink:
nla_put_u16(skb, MPTCP_PM_ADDR_ATTR_PORT, ntohs(addr->port))
Where addr->port is defined as __be16.
No functional change intended.
