2016-09-20openvswitch: avoid resetting flow key while installing new flow.pravin shelar
since commit commit db74a3335e0f6 ("openvswitch: use percpu flow stats") flow alloc resets flow-key. So there is no need to reset the flow-key again if OVS is using newly allocated flow-key. Signed-off-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S. Miller <davem@davemloft.net>
2016-09-20openvswitch: Fix Frame-size larger than 1024 bytes warning.pravin shelar
There is no need to declare separate key on stack, we can just use sw_flow->key to store the key directly. This commit fixes following warning: net/openvswitch/datapath.c: In function ‘ovs_flow_cmd_new’: net/openvswitch/datapath.c:1080:1: warning: the frame size of 1040 bytes is larger than 1024 bytes [-Wframe-larger-than=] Signed-off-by: Pravin B Shelar <pshelar@ovn.org> Signed-off-by: David S.

2016-09-20mac80211: Use rhltable instead of rhashtableHerbert Xu
mac80211 currently uses rhashtable with insecure_elasticity set to true. The latter is because of duplicate objects. What's more, mac80211 walks the rhashtable chains by hand which is broken as rhashtable may contain multiple tables due to resizing or rehashing. This patch fixes it by converting it to the newly added rhltable interface which is designed for use with duplicate objects. With rhltable a lookup returns a list of objects instead of a single one. This is then fed into the existing for_each_sta_info macro. This patch also deletes the sta_addr_hash function since rhashtable defaults to jhash.

Sample use case of how this is encoded: user space via tuntap (or a connected VM/Machine/container) encodes the tcindex TLV. Sample use case of decoding: IFE action decodes it and the skb->tc_index is then used to classify. So something like this for encoded ICMP packets: .. first decode then reclassify... skb->tcindex will be set sudo $TC filter add dev $ETH parent ffff: prio 2 protocol 0xbeef \ u32 match u32 0 0 flowid 1:1 \ action ife decode reclassify ...next match the decode icmp packet... sudo $TC filter add dev $ETH parent ffff: prio 4 protocol ip \ u32 match ip protocol 1 0xff flowid 1:1 \ action continue ... last classify it using the tcindex classifier and do someaction.. sudo $TC filter add dev $ETH parent ffff: prio 5 protocol ip \ handle 0x11 tcindex classid 1:1 \ action blah..

If force_bredr is set SMP BR/EDR channel should also be for non-SC capable controllers. Since hcidev flag is persistent wrt power toggle it can be already set when calling smp_register().
