Edward Cree says: ==================== sfc: encap offloads on EF10 EF10 NICs from the 8000 series onwards support TX offloads (checksumming, TSO) on VXLAN- and NVGRE-encapsulated packets. This series adds driver support for these offloads. Changes from v1: * Fix 'no TXQ of type' error handling in patch #1 (and clear up the misleading comment that inspired the wrong version) * Add comment in patch #5 explaining what the deal with TSOv3 is ==================== Signed-off-by:David S. Miller <davem@davemloft.net>

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:

Nothing yet creates inner csum TXQs; just change all references to EFX_TXQ_TYPE_OFFLOAD to the new EFX_TXQ_TYPE_OUTER_CSUM. 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). Correct a misleading comment on efx_hard_start_xmit(). Signed-off-by:

These are never modified, so constify them to allow the compiler to place them in read-only memory. This moves about 25kB to read-only memory as seen by the output of the size command.

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:
