For such devices, tailroom reservation can be skipped if all the keys are programmed into the hardware (i.e software crypto is not used for any of the keys) and none of the keys wants software to generate Michael MIC.

What would happen is the second hint would schedule delayed work in to catch a timeout but since we are never processing it given that the hint was already applied we'd always hit the timeout and and restore regulatory settings back to world regulatory domain. This is fixed by simply avoiding sheduling work if the hint was already applied. Tested-by: Felix Fietkau <nbd@openwrt.org> Reported-by: Felix Fietkau <nbd@openwrt.org> Signed-off-by: Luis R.

This is heavily based on the patch by Arnaldo that added recvmmsg. I wrote a microbenchmark to test the performance gains of using this new syscall: http://ozlabs.org/~anton/junkcode/sendmmsg_test.c The test was run on a ppc64 box with a 10 Gbit network card. The benchmark can send both UDP and RAW ethernet packets. 64B UDP batch pkts/sec 1 804570 2 872800 (+ 8 %) 4 916556 (+14 %) 8 939712 (+17 %) 16 952688 (+18 %) 32 956448 (+19 %) 64 964800 (+20 %) 64B raw socket batch pkts/sec 1 1201449 2 1350028 (+12 %) 4 1461416 (+22 %) 8 1513080 (+26 %) 16 1541216 (+28 %) 32 1553440 (+29 %) 64 1557888 (+30 %) We see a 20% improvement in throughput on UDP send and 30% on raw socket send.

I believe it was a wrong move. This slows down concurrent dumps, making good old /proc/net/ files faster than rtnetlink in some situations. This occurred to me because one "ip link show dev ..." was _very_ slow on a workload adding/removing network devices in background. All dump callbacks are able to use RCU locking now, so this patch does roughly a revert of commits : 1c2d670f366 : [RTNETLINK]: Hold rtnl_mutex during netlink dump callbacks 6313c1e0992 : [RTNETLINK]: Remove unnecessary locking in dump callbacks This let writers fight for rtnl mutex and readers going full speed. It also takes care of phonet : phonet_route_get() is now called from rcu read section.

This guarantees that speed_hi will be zeroed correctly if the called callback doesn't explicitely set it: we are sure we don't get a corrupted speed from the underlying driver. We also take care of setting the cmd field appropriately (ETHTOOL_GSET/SSET). This applies to dev_ethtool_get_settings(), which now makes sure it sets up that ethtool command parameter correctly before passing it to drivers. This also means that whoever calls dev_ethtool_get_settings() does not have to clean the ethtool command parameter. This function also becomes an exported symbol instead of an inline.

Also, it is possible for failover to take place even though the new active slave does not have link up, and in that case the peer notification should be deferred until it does. Change ipv4 and ipv6 so they do not automatically send peer notifications on bonding failover. Change the bonding driver to send separate NETDEV_NOTIFY_PEERS notifications when the link is up, as many times as requested. Since it does not directly control which protocols send notifications, make num_grat_arp and num_unsol_na aliases for a single parameter. Bump the bonding version number and update its documentation.
