2018-08-07i40e: add helper function for copying strings from stat arraysJacob Keller
Many of the ethtool statistics use the same basic logic for copying strings into the supplied buffer. A set of stats are stored in a const array of i40e_stats structures, and we apply these all together. Simplify the stats code by introducing a helper function which can take a stats array and copy the strings into the buffer, updating the buffer pointer as we go. We use a macro to implement i40e_add_stat_strings so that ARRAY_SIZE can be used on the array passed in. This ensures that we always use the matching size in __i40e_add_stat_strings. More complex stats currently do not use i40e_stats arrays, usually due to custom formatted strings, or because the stats are not laid out in the expected way. These stats will be updated to use the helper function in separate future patches.

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.

We add the delta to locally maintained packet length register and check for overflow, since add of negative value must overflow if result is positive.

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. Call this from mlxsw_afa_fwd_entry_ref_destroy() to make the _fwd_entry_ref_create() and _fwd_entry_ref_destroy() pair of calls a NOP.

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. Therefore replace that warning with an error for this specific case.

The rdma_netdev flow is switched to use the netdev common priv_destructor instead of the special free_rdma_netdev and the IPOIB ULP adjusted: - priv_destructor needs to switch to point to the ULP's destructor which will then call the rdma_ndev's in the right order - We need to be careful around the error unwind of register_netdev as it sometimes calls priv_destructor on failure - ULPs need to use ndo_init/uninit to ensure proper ordering of failures around register_netdev Switching to priv_destructor is a necessary pre-requisite to using the rtnl new_link mechanism.

2018-08-01net: stmmac: Fix WoL for PCI-based setupsJose Abreu
WoL won't work in PCI-based setups because we are not saving the PCI EP state before entering suspend state and not allowing D3 wake. Fix this by using a wrapper around stmmac_{suspend/resume} which correctly sets the PCI EP state. Signed-off-by: Jose Abreu <joabreu@synopsys.com> Cc: David S.
