6.10-stable review patch. If anyone has any objections, please let me know.
------------------
From: Asbjørn Sloth Tønnesen <ast@xxxxxxxxxxx>
[ Upstream commit 09a45a5553792bbf20beba0a1ac90b4692324d06 ]
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.
