[PATCH mptcp-next 0/2] mptcp: MIB counter for invalid option

[Gang Yan <gang.yan@linux.dev>]

From: Gang Yan <yangang@kylinos.cn>

This series is designed for [1].

Patch 1 passes the 'net' to options parser, I used to use
dev_net(skb->dev) for MIB counters, but the AI reported it is not
suitable for this. This patch has no functional change.

Patch 2 adds the InvalidOptionRx counter, and increments it when
receive the invalid options.

The packetdill testcase is submitted, and can be reviewed in [2].
