I think it would be better to drop MPTCP_PM_MAX_ADDR and keep
MPTCP_PM_ADDR_MAX in pm_netlink.c where it is used. Each PM can decide
what's the maximum number of addresses it can support.
MPTCP_PM_MAX_ADDR seems to be a left over from a previous implementation
of a PM that has not been upstreamed but replaced by the Netlink PM later.
Also, please always add "net" or "net-next" prefix in the subject of
your email to help -net maintainers. Do not hesitate to look at the
netdev FAQ for more details.
Here this patch looks like a fix so you should have [PATCH net] and a
"Fixes" tag. I guess for this patch you can use:
Fixes: 1b1c7a0ef7f3 ("mptcp: Add path manager interface")
That's where MPTCP_PM_MAX_ADDR has been introduced. It was already not
used and never used later.
Cheers,
Matt
