The IPA driver depends on some SMEM functionality (qcom_smem_init(), qcom_smem_alloc(), and qcom_smem_virt_to_phys()), but this is not reflected in the configuration dependencies. Add a dependency on QCOM_SMEM to avoid attempts to build the IPA driver without SMEM. This avoids a link error for certain configurations. Reported-by:

Patch didn't fix any issue, just improve parse flow and align ipv4 parse flow with ipv6 parse flow. Currently ipv4 kenguru parser first check IP protocol(TCP/UDP) and then destination IP address. Patch introduce reverse ipv4 parse, first destination IP address parsed and only then IP protocol. This would allow extend capability for packet L4 parsing and align ipv4 parsing flow with ipv6.

bareudp_dellink() only needs the device list to hand it to unregister_netdevice_queue(). We can pass NULL in, and unregister_netdevice_queue() will do the unregistering. There is no chance for batching on the error path, anyway. Suggested-by:

The SFP MSA defines two option bits in byte 65 to indicate how the Rx_LOS signal on SFP pin 8 behaves: bit 2 - Loss of Signal implemented, signal inverted from standard definition in SFP MSA (often called "Signal Detect"). bit 1 - Loss of Signal implemented, signal as defined in SFP MSA (often called "Rx_LOS"). Clearly, setting both bits results in a meaningless situation: it would mean that LOS is implemented in both the normal sense (1 = signal loss) and inverted sense (0 = signal loss). Unfortunately, there are modules out there which set both bits, which will be initially interpret as "inverted" sense, and then, if the LOS signal changes state, we will toggle between LINK_UP and WAIT_LOS states. Change our LOS handling to give well defined behaviour: only interpret these bits as meaningful if exactly one is set, otherwise treat it as if LOS is not implemented. Signed-off-by: -

The code that sets the DMA mask to 64 bits is bogus, it is taken from the enetc driver together with the rest of the PCI probing boilerplate. Since this patch is touching the error path to delete err_dma, let's also change the err_alloc_felix label which was incorrect. The kzalloc failure does not need a kfree, but it doesn't hurt either, since kfree works with NULL pointers. Signed-off-by:

Vladimir Oltean says: ==================== Get rid of the switchdev transactional model Changes in v4: - Fixed build error in dsa_loop and build warning in hellcreek driver. - Scheduling the mlxsw SPAN work item regardless of the VLAN add return code, as per Ido's and Petr's request. Changes in v3: - Resolved a build warning in mv88e6xxx and tested that it actually works properly, which resulted in an extra patch (02/11). - Addressed Ido's minor feedback in commit 10/11 relating to a comment. Changes in v2: - Got rid of the vid_begin -> vid_end range too from the switchdev API. - Actually propagating errors from DSA MDB and VLAN notifiers. This series comes after the late realization that the prepare/commit separation imposed by switchdev does not help literally anybody: https://patchwork.kernel.org/project/netdevbpf/patch/20201212203901.351331-1-vladimir.oltean@nxp.com/ We should kill it before it inflicts even more damage to the error handling logic in drivers. Also remove the unused VLAN ranges feature from the switchdev VLAN objects, which simplifies all drivers by quite a bit. ==================== Link: https://lore.kernel.org/r/20210109000156.1246735-1-olteanv@gmail.comSigned-off-by:

As of commit 457e20d6 ("mlxsw: spectrum_switchdev: Avoid returning errors in commit phase"), the mlxsw driver performs the VLAN object offloading during the prepare phase. So conversion just seems to be a matter of removing the code that was running in the commit phase. Ido Schimmel explains that the reason why mlxsw_sp_span_respin is called unconditionally is because the bridge driver will ignore -EOPNOTSUPP and actually add the VLAN on the bridge device - see commit 9c86ce2c ("net: bridge: Notify about bridge VLANs") and commit ea472175 ("mlxsw: spectrum_switchdev: Ignore bridge VLAN events"). Since the VLAN was successfully added on the bridge device, mlxsw_sp_span_respin_work() should be able to resolve the egress port for a packet that is mirrored to a gre tap and passes through the bridge device. Therefore keep the logic as it is. Signed-off-by:
