ath79: set mib-poll-interval on mdio0 attached ar83xx switch
Commit "generic: ar8216: add mib_poll_interval switch attribute" sets
mib-poll-interval as disabled by default (was set to 2s), so it makes
switch LEDs trigger disfunctional on devices which don't have
mib-poll-interval set.
So this patch sets mib-poll-interval to 500ms on devices which have
ar83xx switch connected to mdio0 bus, as the same value was set for
built in switches in 443fc9ac35 ("ath79: use ar8216 for builtin
switch").
Some measurements performed on TP-Link Archer C7-v5:
mib-type=0, mib-poll-interval=500ms (10s pidstat)
Average: %usr %system %guest %wait %CPU CPU Command
Average: 0.00 1.93 0.00 0.00 1.93 - kworker/0:2
iperf3 (30s): 334 Mbits/sec
mib-type=0, mib-poll-interval=2s (10s pidstat)
Average: %usr %system %guest %wait %CPU CPU Command
Average: 0.00 1.14 0.00 0.00 1.14 - kworker/0:2
iperf3 (30s): 334 Mbits/sec
So it seems like we get 4x faster LED refresh rate for additional 0.8%
CPU load.
