2018-08-07net: systemport: Add support for WAKE_FILTERFlorian Fainelli
The SYSTEMPORT MAC allows up to 8 filters to be programmed to wake-up from LAN. Verify that we have up to 8 filters and program them to the appropriate RXCHK entries to be matched (along with their masks). We need to update the entry and exit to Wake-on-LAN mode to keep the RXCHK engine running to match during suspend, but this is otherwise fairly similar to Magic Packet detection.

Allow propagating ethtool::rxnfc programming to the CPU/management port such that it is possible for such a CPU to perform e.g: Wake-on-LAN using filters configured by the switch. We need a tiny bit of cooperation between the switch drivers which is able to do the full flow matching, whereas the CPU/management port might not. The CPU/management driver needs to return -EOPNOTSUPP to indicate an non critical error, any other error code otherwise. Signed-off-by: Florian Fainelli <f.fainelli@gmail.com> Signed-off-by: David S.

2018-08-06ieee802154: hwsim: add replacement for fakelbAlexander Aring
This patch adds a new virtual driver mac802154_hwsim which is based on the fakelb driver. The fakelb driver will get deprecated and hopefully removed someday. The main reason for doing this step is to rename the driver to mac802154_hwsim to have a similar naming scheme as mac80211_hwsim, which is more popular in the 802.11 wireless word and the idea is the same behind this driver. The new features of this driver are to have knowledge about connected edges, which can be changed during runtime. This offers a testing environment for routing protocols e.g. RPL. The default behaviour is still as fakelb: two radios connected to each other. New added radios during runtime will not be connected to other wpan_hwsim instances. The netlink api is not namespace aware on purpose, only the registered wpan_phy's can be moved to namespaces. The physical layer according to wiresless "air" communication can be handled across namespaces. Furthermore the edges can be weighted with the LQI value according IEEE 802.15.4 which offers additional handling to mark bad or good connection indicators to other connected virtual phys.

2018-08-05mlxsw: spectrum: Configure MC-aware mode on mlxsw portsPetr Machata
In order to give unicast traffic precedence over BUM traffic, configure multicast-aware mode on all ports. Under multicast-aware regime, when assigning traffic class to a packet, the switch doesn't merely take the value prescribed by the QTCT register. For BUM traffic, it instead assigns that value plus 8. ETS elements for TCs 8..15 thus need to be configured as well. Extend mlxsw_sp_port_ets_init() so that it maps each of them to the same subgroup as their corresponding TC from the range 0..7, such that TCs X and X+8 map to the same subgroup. The existing code configures TCs with strict priority. So far this was immaterial, because each TC had its own subgroup. Now that two TCs share a subgroup it becomes important. TCs are prioritized in order of 7, 6, ..., 0, 15, 14, ..., 8: the higher TCs used for BUM traffic end up being deprioritized. Since that's what's needed, keep that configuration as it is, and configure the new TCs likewise. Finally in mlxsw_sp_port_create(), invoke configuration of QTCTM to enable MC-aware mode on each port.

2018-08-03mlxsw: core_acl_flex_actions: Remove redundant resource destructionNir Dotan
Some ACL actions require the allocation of a separate resource prior to applying the action itself. When facing an error condition during the setup phase of the action, resource should be destroyed. For such actions the destruction was done twice which is dangerous and lead to a potential crash. The destruction took place first upon error on action setup phase and then as the rule was destroyed. The following sequence generated a crash: # tc qdisc add dev swp49 ingress # tc filter add dev swp49 parent ffff: \ protocol ip chain 100 pref 10 \ flower skip_sw dst_ip 192.168.101.1 action drop # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 \ flower skip_sw dst_ip 192.168.101.1 action goto chain 100 \ action mirred egress mirror dev swp4 Therefore add mlxsw_afa_resource_del() as a complement of mlxsw_afa_resource_add() to add symmetry to resource_list membership handling.

2018-08-03mlxsw: core_acl_flex_actions: Return error for conflicting actionsNir Dotan
Spectrum switch ACL action set is built in groups of three actions which may point to additional actions. A group holds a single record which can be set as goto record for pointing at a following group or can be set to mark the termination of the lookup. This is perfectly adequate for handling a series of actions to be executed on a packet. While the SW model allows configuration of conflicting actions where it is clear that some actions will never execute, the mlxsw driver must block such configurations as it creates a conflict over the single terminate/goto record value. For a conflicting actions configuration such as: # tc filter add dev swp49 parent ffff: \ protocol ip pref 10 \ flower skip_sw dst_ip 192.168.101.1 \ action goto chain 100 \ action mirred egress mirror dev swp4 Where it is clear that the last action will never execute, the mlxsw driver was issuing a warning instead of returning an error.

2018-08-03net: hns3: Refine the MSIX allocation for PFJian Shen
The offset of msix number for roce is different between different revision id. We should get it from firmware, instead of a fix value. This patch refines the msix allocation, make it compatible.

2018-08-03net: hns3: Fix MSIX allocation issue for VFJian Shen
The msix number for vf is different, depends on the max vf number. Futherly if the vf supports roce, the offset of msix is not fixed. It's incorrect to fix the msix number to 33. This patch fixes it by querying the msix number from firmware, and adjusting it with roce support.

Current value for a target abort error is 0x010, however, this value should in fact be 0x002. As it stands, the range of error is 0..7 so it is currently never being detected.
