[PATCH net 1/9] mptcp: fix error mibs accounting
From: Mat Martineau <hidden>
Date: 2022-06-28 01:03:11
Also in:
mptcp

From: Paolo Abeni <pabeni@redhat.com>
The current accounting for MP_FAIL and FASTCLOSE is not very
accurate: both can be increased even when the related option is
not really sent. Move the accounting into the correct place.
Fixes: eb7f33654dc1 ("mptcp: add the mibs for MP_FAIL")
Fixes: 1e75629cb964 ("mptcp: add the mibs for MP_FASTCLOSE")
