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.
