Now that the icplus driver has been fixed all PHY drivers supporting interrupts have both callbacks (config_intr and ack_interrupt) implemented - as it should be. Therefore phy_drv_supports_irq() can be changed now to check for both callbacks being implemented. Signed-off-by:

Michał Mirosław says: ==================== Remove VLAN.CFI overload Fix BPF code/JITs to allow for separate VLAN_PRESENT flag storage and finally move the flag to separate storage in skbuff. This is final step to make CLAN.CFI transparent to core Linux networking stack. An #ifdef is introduced temporarily to mark fragments masking VLAN_TAG_PRESENT. This is removed altogether in the final patch. ==================== Signed-off-by: -

netperf udp stream shows that eth_type_trans takes certain cpu, so adjust the mac address check order, and firstly check if it is device address, and only check if it is multicast address only if not the device address. After this change: To unicast, and skb dst mac is device mac, this is most of time reduce a comparision To unicast, and skb dst mac is not device mac, nothing change To multicast, increase a comparision Before: 1.03% [kernel] [k] eth_type_trans After: 0.78% [kernel] [k] eth_type_trans Signed-off-by:

Jeff Kirsher says: ==================== 40GbE Intel Wired LAN Driver Updates 2018-11-14 This series contains updates to i40e and virtchnl. Lance Roy updates i40e to use lockdep_assert_held() instead of spin_is_locked(), since it is better suited to check locking requirements. Jan improves the code readability in XDP by adding the use of a local variable. Provides protection on methods that create/modify/destroy VF's via locking mechanism to prevent unstable behaviour and potential kernel panics. Krzysztof adds a hardware capability flag to indicate whether firmware supports stopping the LLDP agent. Patryk replaces the use of strncpy() with strlcpy() to ensure the buffer is NULL terminated. Mitch fixes the issue of trying to start nway on devices that do not support auto-negotiation, by checking the autoneg state before attempting to restart nway. Alice updates virtchnl to keep the checks all together for ease of readability and consistency. Also fixed a "off by one" error in the number of traffic classes being calculated. Richard fixed VF port VLANs, where the priority bits were incorrectly set because the incorrect shift and mask bits were being used. Alan adds a bit to set and check if a timeout recovery is already pending to prevent overlapping transmit timeout recovery. ==================== Signed-off-by: -

Ido Schimmel says: ==================== mlxsw: spectrum: acl: Introduce ERP sharing by multiple masks Jiri says: The Spectrum-2 hardware has limitation number of ERPs per-region. In order to accommodate more masks than number of ERPs, the hardware supports to insert rules with delta bits. By that, the rules with masks that differ in up-to 8 consecutive bits can share the same ERP. Patches 1 and 2 fix couple of issues that would appear in existing selftests after adding delta support Patch 3 introduces a generic object aggregation library. Now it is static, but it will get extended for recalculation of aggregations in the future in order to reach more optimal aggregation. Patch 4 just simply converts existing ERP code to use the objagg library instead of a rhashtable. Patches 5-9 do more or less small changes to prepare ground for the last patch. Patch 10 fills-up delta callbacks of objagg library and utilizes the delta bits for rule insertion. The last patch adds selftest to test the mlxsw Spectrum-2 delta flows. ==================== Signed-off-by: -

The device requires that the master mask of each region will be composed from a logical OR between all the unmasked bits in the region. Currently, this is just a logical OR between all the eRPs used in the region, but the next patch is going to introduce delta bits support which need to be taken into account as well. Since the eRP does not include the delta bits, pass the key pointer to mlxsw_sp_acl_erp_master_mask_set/clear instead. Convert key->mask to the bitmap on fly. Signed-off-by:

Currently the ERPs are tracked internally in a hashtable. Benefit from the newly introduced objagg library and use it to track ERPs. At this point, there is no nesting of objects done, as the delta_create callback always returns -EOPNOTSUPP. On the way, add "mask" into ERP mask get and set functions and struct names.

This lib tracks objects which could be of two types: 1) root object 2) nested object - with a "delta" which differentiates it from the associated root object The objects are tracked by a hashtable and reference-counted. User is responsible of implementing callbacks to create/destroy root entity related to each root object and callback to create/destroy nested object delta. Signed-off-by: -

Match on a port range: ------------------------- $ tc filter add dev enp4s0 protocol ip parent ffff:\ prio 1 flower ip_proto tcp dst_port range 20-30 skip_hw\ action drop $ tc -s filter show dev enp4s0 parent ffff: filter protocol ip pref 1 flower chain 0 filter protocol ip pref 1 flower chain 0 handle 0x1 eth_type ipv4 ip_proto tcp dst_port range 20-30 skip_hw not_in_hw action order 1: gact action drop random type none pass val 0 index 1 ref 1 bind 1 installed 85 sec used 3 sec Action statistics: Sent 460 bytes 10 pkt (dropped 10, overlimits 0 requeues 0) backlog 0b 0p requeues 0 2.

We already have a workaround for a couple of switches whose internal PHYs only have the Marvel OUI, but no model number. We detect such PHYs and give them the 6390 ID as the model number. However the mv88e6161 has two SERDES interfaces in the same address range as its internal PHYs. These suffer from the same problem, the Marvell OUI, but no model number. As a result, these SERDES interfaces were getting the same PHY ID as the mv88e6390, even though they are not PHYs, and the Marvell PHY driver was trying to drive them. Add a special case to stop this from happen. Reported-by:

Jeff Kirsher says: ==================== 100GbE Intel Wired LAN Driver Updates 2018-11-13 This series contains updates to the ice driver only. Brett cleans up debug print messages by removing useless or duplicate messages, and make sure we assign the hardware head pointer to head instead of the software head pointer. Resolved an issue when disabling SRIOV we were trying to stop queues multiple times, so make sure we disable SRIOV before stopping transmit and receive queues for VF. Tony fixes a potential NULL pointer dereference during a VF reset. Anirudh resolves an issue where we were releasing the VSI before removing the VSI scheduler node, which was resulting in an error "Failed to set LAN Tx queue context, error: -1". Also fixed the guaranteed number of VSIs available and used by discovering the device capabilities to determine the 'guar_num_vsi' per function, rather than always using the theoretical max number of VSIs every time. Dave avoids a deadlock by nesting RTNL locking, so added a boolean to determine if the RTNL lock is already held. Lev fixes bad mask values which would break compilation. Piotr increases the receive queue disable timeout since it can take additional time to finish all pending queue requests. Usha resolves an issue of VLAN priority tagged traffic not appearing on all traffic classes, which was causing ETS bandwidth shaping to not work as expected. Henry fixes the reset path to cleanup the old scheduler tree before rebuilding it. Md Fahad removes a unnecessary check which was causing a driver load error on platforms with more than 128 cores. ==================== Signed-off-by: -

The "FE bit" in the description means the last description for a packets. When HW GRO enable, HW write data to ring every packet/buffer, there is greater probability that driver handle with the describtion but HW still not set the "FE bit". When drier handle the packet and HW still not set "FE bit", driver stores skb and bd_num in rx ring, and continue to use the skb and bd_num in next napi. Signed-off-by:

Move IRQ configuration for IP101A/G from config_init to config_intr callback. Reasons: 1. This allows phylib to disable interrupts if needed. 2. Icplus was the only driver supporting interrupts w/o defining a config_intr callback. Now we can add a phylib plausibility check disabling interrupt mode if one of the two irq-related callbacks isn't defined. I don't own hardware with this PHY, and the change is based on the datasheet for IP101A LF (which is supposed to be register-compatible with IP101A/G). Change is compile-tested only. Signed-off-by:
