====================
mptcp: misc fixes for v6.17-rc6

Here are various unrelated fixes:

- Patch 1: Fix a wrong attribute type in the MPTCP Netlink specs. A fix
for v6.7.

- Patch 2: Avoid mentioning a deprecated MPTCP sysctl knob in the doc. A
fix for v6.15.

- Patch 3: Handle new warnings from ShellCheck v0.11.0. This prevents
some warnings reported by some CIs. If it is not a good material for
'net', please drop.
