While working on another tag_8021q driver implementation, some things became apparent: - It is not mandatory for a DSA driver to offload the tag_8021q VLANs by using the VLAN table per se. For example, it can add custom TCAM rules that simply encapsulate RX traffic, and redirect & decapsulate rules for TX traffic. For such a driver, it makes no sense to receive the tag_8021q configuration through the same callback as it receives the VLAN configuration from the bridge and the 8021q modules. - Currently, sja1105 (the only tag_8021q user) sets a priv->expect_dsa_8021q variable to distinguish between the bridge calling, and tag_8021q calling. That can be improved, to say the least. - The crosschip bridging operations are, in fact, stateful already. The list of crosschip_links must be kept by the caller and passed to the relevant tag_8021q functions. So it would be nice if the tag_8021q configuration was more self-contained. This patch attempts to do that. Create a struct dsa_8021q_context which encapsulates a struct dsa_switch, and has 2 function pointers for adding and deleting a VLAN. These will replace the previous channel to the driver, which was through the .port_vlan_add and .port_vlan_del callbacks of dsa_switch_ops. Also put the list of crosschip_links into this dsa_8021q_context. Drivers that don't support cross-chip bridging can simply omit to initialize this list, as long as they dont call any cross-chip function. The sja1105_vlan_add and sja1105_vlan_del functions are refactored into a smaller sja1105_vlan_add_one, which now has 2 entry points: - sja1105_vlan_add, from struct dsa_switch_ops - sja1105_dsa_8021q_vlan_add, from the tag_8021q ops But even this change is fairly trivial. It just reflects the fact that for sja1105, the VLANs from these 2 channels end up in the same hardware table. However that is not necessarily true in the general sense (and that's the reason for making this change). The rest of the patch is mostly plain refactoring of "ds" -> "ctx". The dsa_8021q_context structure needs to be propagated because adding a VLAN is now done through the ops function pointers inside of it. Signed-off-by:

There is no point in calling dsa_port_setup_8021q_tagging for each individual port. Additionally, it will become more difficult to do that when we'll have a context structure to tag_8021q (next patch). So refactor this now. Signed-off-by:

Remove the tx_queue->handle_tso function pointer, and just use tx_queue->tso_version to decide which function to call, thus removing an indirect call from the fast path. Instead of passing a tso_v2 flag to efx_mcdi_tx_init(), set the desired tx_queue->tso_version before calling it. In efx_mcdi_tx_init(), report back failure to obtain a TSOv2 context by setting tx_queue->tso_version to 0, which will cause the TX path to use the GSO-based fallback. Signed-off-by:

Make it possible to have an arbitrary mapping from types to labels, because when we add inner-csum-offload TXQs there will no longer be a convenient nesting hierarchy of NIC types (EF10 will have inner-csum TXQs, while Siena will have HIGHPRI).

Each MDB entry is encoded in a nested netlink attribute called 'MDBA_MDB_ENTRY'. In turn, this attribute contains another nested attributed called 'MDBA_MDB_ENTRY_INFO', which encodes a single port group entry within the MDB entry. The cited commit added the ability to restart a dump from a specific port group entry. However, on failure to add a port group entry to the dump the entire MDB entry (stored in 'nest2') is removed, resulting in missing port group entries. Fix this by finalizing the MDB entry with the partial list of already encoded port group entries.

This adds functionality to report driver stats to Hypervisor. (Users may want to turn this feature off as a matter of privacy so a "report-stats" flag is added as an ethtool priv option. It is also disabled by default.) The hypervisor would trigger a stats report in case "too many" packets dropped; the stats would be useful in debugging stuck queues. A "stats_report_trigger_cnt" stat is added to count the number of times the hypervisor attempts to trigger stats report. A timer is also added so that when report-stats is enabled, stat are updated once every 20 seconds. Reviewed-by:
