The current code assumes that we will always have at least 2 rx rings, 1 will be used as an aggregation ring for TPA and jumbo page placements. However, it is possible, especially on a VF, that there is only 1 rx ring available. In this scenario, the current code will fail to initialize. To handle it, we need to properly set up only 1 ring without aggregation. Set a new flag BNXT_FLAG_NO_AGG_RINGS for this condition and add logic to set up the chip to place RX data linearly into a single buffer per packet.

With the added support for the bnxt_re RDMA driver, both drivers can be allocating completion rings in any order. The firmware does not know which completion ring should be receiving async events. Add an extra step to tell firmware the completion ring number for receiving async events after bnxt_en allocates the completion rings.

In order to properly support TX rate limiting in SRIOV VF functions or NPAR functions, firmware needs better control over tx ring allocations. The new scheme requires the driver to reserve the number of tx rings and to query to see if the requested number of tx rings is reserved. The driver will use the new scheme when the firmware interface spec is 1.6.1 or newer. Signed-off-by: Michael Chan <michael.chan@broadcom.com> Signed-off-by: David S. Miller <davem@davemloft.net>

The existing hardware RFS mode uses one hardware RSS context block per ring just to calculate the RSS hash. This is very wasteful and prevents VF functions from using it. The new hardware mode shares the same hardware RSS context for RSS placement and RFS steering. This allows VFs to enable RFS.

The advertising field is closely related to the auto_link_speeds field. The former is the user setting while the latter is the firmware setting. Both should be u16. We should use the advertising field in bnxt_get_link_ksettings because the auto_link_speeds field may not be updated with the latest from the firmware yet.

The IRQ is disabled by writing to the completion ring doorbell. This should be done before the hardware completion ring is freed for correctness. The current code disables IRQs after all the completion rings are freed. Fix it by calling bnxt_disable_int_sync() before freeing the completion rings. Rearrange the code to avoid forward declaration. Signed-off-by: Michael Chan <michael.chan@broadocm.com> Signed-off-by: David S. Miller <davem@davemloft.net>

There are three functions which would invoke the ipvlan_count_rx. They are ipvlan_process_multicast, ipvlan_rcv_frame, and ipvlan_nf_input. The former two functions already use the ipvlan directly before ipvlan_count_rx, and ipvlan_nf_input gets the ipvlan from ipvl_addr->master, it is not possible to be NULL too. So the ipvlan pointer check is unnecessary in ipvlan_count_rx. Signed-off-by: Gao Feng <fgao@ikuai8.com> Signed-off-by: David S. Miller <davem@davemloft.net>

Pull networking fixes from David Miller: 1) Various ipvlan fixes from Eric Dumazet and Mahesh Bandewar. The most important is to not assume the packet is RX just because the destination address matches that of the device. Such an assumption causes problems when an interface is put into loopback mode. 2) If we retry when creating a new tc entry (because we dropped the RTNL mutex in order to load a module, for example) we end up with -EAGAIN and then loop trying to replay the request. But we didn't reset some state when looping back to the top like this, and if another thread meanwhile inserted the same tc entry we were trying to, we re-link it creating an enless loop in the tc chain. Fix from Daniel Borkmann. 3) There are two different WRITE bits in the MDIO address register for the stmmac chip, depending upon the chip variant. Due to a bug we could set them both, fix from Hock Leong Kweh. 4) Fix mlx4 bug in XDP_TX handling, from Tariq Toukan. * git://git.kernel.org/pub/scm/linux/kernel/git/davem/net: net: stmmac: fix incorrect bit set in gmac4 mdio addr register r8169: add support for RTL8168 series add-on card. net: xdp: remove unused bfp_warn_invalid_xdp_buffer() openvswitch: upcall: Fix vlan handling. ipv4: Namespaceify tcp_tw_reuse knob net: korina: Fix NAPI versus resources freeing net, sched: fix soft lockup in tc_classify net/mlx4_en: Fix user prio field in XDP forward tipc: don't send FIN message from connectionless socket ipvlan: fix multicast processing ipvlan: fix various issues in ipvlan_process_multicast()

Networking stack accelerate vlan tag handling by keeping topmost vlan header in skb. This works as long as packet remains in OVS datapath. But during OVS upcall vlan header is pushed on to the packet. When such packet is sent back to OVS datapath, core networking stack might not handle it correctly. Following patch avoids this issue by accelerating the vlan tag during flow key extract. This simplifies datapath by bringing uniform packet processing for packets from all code paths. Fixes: 5108bbad ("openvswitch: add processing of L3 packets").
