[PATCHv2 iproute2 net-next] nstat: add sctp snmp support
From: Hangbin Liu <hidden>
Date: 2016-09-05 03:35:15
SCTP module was not load by default. But this should be OK since we will not load table if fdopen() failed, also opening the proc file won't load SCTP kernel module. Signed-off-by: Hangbin Liu <redacted> --- misc/nstat.c | 18 ++++++++++++++++++ 1 file changed, 18 insertions(+)
