Subject: [PATCH net-next 0/2] net: snmp: minor optimizations

From: Eric Dumazet <edumazet@...gle.com>

Fetching many SNMP counters on hosts with large number of cpus
takes a lot of time. mptcp still uses the old non-batched
fashion which is not cache friendly.

Eric Dumazet (2):
  net: snmp: inline snmp_get_cpu_field()
  mptcp: use batch snmp operations in mptcp_seq_show()
