There's not really any nice way to assign the lock classes when we split subdev indices into type+inst, and saves a few bytes in the structs when a subdev has no need for it. Signed-off-by: Ben Skeggs <bskeggs@redhat.com> Reviewed-by: Lyude Paul <lyude@redhat.com>

If the SKU_ID doesn't match, we don't increment the pointer and keep checking the same TLV over and over again. We need to increment the pointer in all situtations, namely if the TLV is not a SKU_ID, if the SKU_ID matched or if the SKU_ID didn't match.

2021-02-11iwlwifi: mvm: reduce the print severity of failing getting NIC tempGolan Ben Ami
Currently, for all devices and families, failing getting the temp from the fw is indicated in the log as ERR. This is too severe for two reasons: 1. The driver has a fall back - and schedules the next temp read immediately after failing to read temp from the fw. 2. The temp read implementation in the fw is different between HWs, and on older devices the flow is a-sync and may timeout. Reducing the print severity from ERR to WARN will allow to track the issue if it will appear many times, but not frighten users if it appears once.

Return value of the iwl_mvm_load_nvm_to_nic func is not analyzed. If load NVM to nic func fails and NVM is not loaded to fw properly, then fw may behave badly and lead to some strange issue.

2021-02-11iwlwifi: mvm: simplify iwl_mvm_dbgfs_registerEmmanuel Grumbach
No need to pass the dbgfs_dir just to assign it to mvm. Assign to mvm and then call iwl_mvm_dbgfs_register. This is a preparation towards the addition of a delayed op_mode_start flow. This will allow to split the op_mode_start flow. Registration to debugfs must happen after we register to mac80211 and the registration to mac80211 will soon be delayed in certain cases. In order not to have to remember the debugfs_dir in a separate variable, just set it into the mvm structure so that it can be usable later.

Pavel pointed that the return of dma_addr_t in otx2_alloc_rbuf/__otx2_alloc_rbuf() seem suspicious because a negative error code may be returned in some cases. For a dma_addr_t, the error code such as -ENOMEM does seem a valid value, so we can't judge if the buffer allocation fail or not based on that value.

2021-02-10net: mhi: Add mbim protoLoic Poulain
MBIM has initially been specified by USB-IF for transporting data (IP) between a modem and a host over USB. However some modern modems also support MBIM over PCIe (via MHI). In the same way as QMAP(rmnet), it allows to aggregate IP packets and to perform context multiplexing. This change adds minimal MBIM data transport support to MHI, allowing to support MBIM only modems. MBIM being based on USB NCM, it reuses and copy some helpers/functions from the USB stack (cdc-ncm, cdc-mbim). Note that is a subset of the CDC-MBIM specification, supporting only transport of network data (IP), there is no support for DSS. Moreover the multi-session (for multi-pdn) is not supported in this initial version, but will be added latter, and aligned with the cdc-mbim solution (VLAN tags).

2021-02-10net: mhi: Add protocol supportLoic Poulain
MHI can transport different protocols, some are handled at upper level, like IP and QMAP(rmnet/netlink), but others will need to be inside MHI net driver, like mbim. This change adds support for protocol rx and tx_fixup callbacks registration, that can be used to encode/decode the targeted protocol.

2021-02-10i40e: VLAN field for flow directorPrzemyslaw Patynowski
Allow user to specify VLAN field and add it to flow director. Show VLAN field in "ethtool -n ethx" command. Handle VLAN type and tag field provided by ethtool command. Refactored filter addition, by replacing static arrays with runtime dummy packet creation, which allows specifying VLAN field. Previously, VLAN field was omitted.

2021-02-10i40e: Add flow director support for IPv6Przemyslaw Patynowski
Flow director for IPv6 is not supported. 1) Implementation of support for IPv6 flow director. 2) Added handlers for addition of TCP6, UDP6, SCTP6, IPv6. 3) Refactored legacy code to make it more generic. 4) Added packet templates for TCP6, UDP6, SCTP6, IPv6. 5) Added handling of IPv6 source and destination address for flow director. 6) Improved argument passing for source and destination portin TCP6, UDP6 and SCTP6. 7) Added handling of ethtool -n for IPv6, TCP6,UDP6, SCTP6. 8) Used correct bit flag regarding FLEXOFF field of flow director data descriptor. Without this patch, there would be no support for flow director on IPv6, TCP6, UDP6, SCTP6. Tested based on x710 datasheet by using: ethtool -N enp133s0f0 flow-type tcp4 src-port 13 dst-port 37 user-def 0x44142 action 1 ethtool -N enp133s0f0 flow-type tcp6 src-port 13 dst-port 40 user-def 0x44142 action 2 ethtool -N enp133s0f0 flow-type udp4 src-port 20 dst-port 40 user-def 0x44142 action 3 ethtool -N enp133s0f0 flow-type udp6 src-port 25 dst-port 40 user-def 0x44142 action 4 ethtool -N enp133s0f0 flow-type sctp4 src-port 55 dst-port 65 user-def 0x44142 action 5 ethtool -N enp133s0f0 flow-type sctp6 src-port 60 dst-port 40 user-def 0x44142 action 6 ethtool -N enp133s0f0 flow-type ip4 src-ip 1.1.1.1 dst-ip 1.1.1.4 user-def 0x44142 action 7 ethtool -N enp133s0f0 flow-type ip6 src-ip fe80::3efd:feff:fe6f:bbbb dst-ip fe80::3efd:feff:fe6f:aaaa user-def 0x44142 action 8 Then send traffic from client which matches the criteria provided to ethtool. Observe that packets are redirected to user set queues with ethtool -S <interface> Signed-off-by: Przemyslaw Patynowski <przemyslawx.patynowski@intel.com> Tested-by: Tony Brelinski <tonyx.brelinski@intel.com> Signed-off-by: Tony Nguyen <anthony.l.nguyen@intel.com>
