State of autonegotiation may have changed but is not yet refreshed.
Make sure ethtool respects the NFP_PORT_CHANGED flag when looking

If reading new state of the port failed, mark the port back as CHANGED.
This way next user state request will trigger refresh, which will
hopefully succeed.

Encapsulate port information into struct nfp_port. nfp_port will
soon be extended to contain devlink_port information. It also makes

We only support core NIC apps which have vNICs for each physical port/
split and no representors right now. Enforce that either each vNIC has
a NSP eth_table entry or if NSP port table is not available none do.
One scenario this will prevent from happening is user force-loading
wrong firmware file if FW app requires different firmwares per media
config.
While at it move some code to nfp_net_pf_alloc_vnic() to make it
counter-match nfp_net_pf_free_vnic() better.

vNIC is a PCIe-side abstraction NFP firmwares supported by this
driver use. It was initially meant to represent a device port
and therefore a netdev but today should be thought of as a way
of grouping descriptor rings and associated state. Advanced apps
will have vNICs without netdevs and ports without a vNIC (using
representors instead).
Make sure code refers to vNICs as vNICs and not ports or netdevs.
No functional changes.

The macsec implementation shouldn't account for rx/tx packets that are
dropped in the netdev framework. The netdev framework itself accounts
for such packets by atomically updating struct net_device`rx_dropped and
struct net_device`tx_dropped fields. Later on when the stats for macsec
link is retrieved, the packets dropped in netdev framework will be
included in dev_get_stats() after calling macsec.c`macsec_get_stats64()

Some drivers were calling the skb_tx_timestamp() function only when
a hardware timestamp was not requested. Now that applications can use
the SOF_TIMESTAMPING_OPT_TX_SWHW option to request both software and

Current largesend and checksum offload feature in ibmveth driver,
- Source VM sends the TCP packets with ip_summed field set as
CHECKSUM_PARTIAL and TCP pseudo header checksum is placed in
checksum field
- CHECKSUM_PARTIAL flag in SKB will enable ibmveth driver to mark
"no checksum" and "checksum good" bits in transmit buffer descriptor
before the packet is delivered to pseries PowerVM Hypervisor
- If ibmveth has largesend capability enabled, transmit buffer descriptors
are market accordingly before packet is delivered to Hypervisor
(along with mss value for packets with length > MSS)
- Destination VM's ibmveth driver receives the packet with "checksum good"
bit set and so, SKB's ip_summed field is set with CHECKSUM_UNNECESSARY
- If "largesend" bit was on, mss value is copied from receive descriptor
into SKB's gso_size and other flags are appropriately set for
packets > MSS size
- The packet is now successfully delivered up the stack in destination VM
The offloads described above works fine for TCP communication among VMs in
the same pseries server ( VM A <=> PowerVM Hypervisor <=> VM B )
We are now enabling support for OVS in pseries PowerVM environment. One of
our requirements is to have ibmveth driver configured in "Trunk" mode, when
they are used with OVS. This is because, PowerVM Hypervisor will no more
bridge the packets between VMs, instead the packets are delivered to
IO Server which hosts OVS to bridge them between VMs or to external
networks (flow shown below),
VM A <=> PowerVM Hypervisor <=> IO Server(OVS) <=> PowerVM Hypervisor
<=> VM B
In "IO server" the packet is received by inbound Trunk ibmveth and then
delivered to OVS, which is then bridged to outbound Trunk ibmveth (shown
below),
Inbound Trunk ibmveth <=> OVS <=> Outbound Trunk ibmveth
In this model, we hit the following issues which impacted the VM
communication performance,
- Issue 1: ibmveth doesn't support largesend and checksum offload features
when configured as "Trunk". Driver has explicit checks to prevent
enabling these offloads.
- Issue 2: SYN packet drops seen at destination VM. When the packet
originates, it has CHECKSUM_PARTIAL flag set and as it gets delivered to
IO server's inbound Trunk ibmveth, on validating "checksum good" bits
in ibmveth receive routine, SKB's ip_summed field is set with
CHECKSUM_UNNECESSARY flag. This packet is then bridged by OVS (or Linux
Bridge) and delivered to outbound Trunk ibmveth. At this point the
outbound ibmveth transmit routine will not set "no checksum" and
"checksum good" bits in transmit buffer descriptor, as it does so only
when the ip_summed field is CHECKSUM_PARTIAL. When this packet gets
delivered to destination VM, TCP layer receives the packet with checksum
value of 0 and with no checksum related flags in ip_summed field. This
leads to packet drops. So, TCP connections never goes through fine.
- Issue 3: First packet of a TCP connection will be dropped, if there is
no OVS flow cached in datapath. OVS while trying to identify the flow,
computes the checksum. The computed checksum will be invalid at the
receiving end, as ibmveth transmit routine zeroes out the pseudo
checksum value in the packet. This leads to packet drop.
- Issue 4: ibmveth driver doesn't have support for SKB's with frag_list.
When Physical NIC has GRO enabled and when OVS bridges these packets,
OVS vport send code will end up calling dev_queue_xmit, which in turn
calls validate_xmit_skb.
In validate_xmit_skb routine, the larger packets will get segmented into
MSS sized segments, if SKB has a frag_list and if the driver to which
they are delivered to doesn't support NETIF_F_FRAGLIST feature.
This patch addresses the above four issues, thereby enabling end to end
largesend and checksum offload support for better performance.
- Fix for Issue 1 : Remove checks which prevent enabling TCP largesend and
checksum offloads.
- Fix for Issue 2 : When ibmveth receives a packet with "checksum good"
bit set and if its configured in Trunk mode, set appropriate SKB fields
using skb_partial_csum_set (ip_summed field is set with
CHECKSUM_PARTIAL)
- Fix for Issue 3: Recompute the pseudo header checksum before sending the
SKB up the stack.
- Fix for Issue 4: Linearize the SKBs with frag_list. Though we end up
allocating buffers and copying data, this fix gives
upto 4X throughput increase.
Note: All these fixes need to be dropped together as fixing just one of
them will lead to other issues immediately (especially for Issues 1,2 & 3).

Driver maintains its primary MAC in a private field which
gets updated when ndo_dev_set_mac() gets called.
However, there are flows where the primary MAC of the device can change
without said NDO being called [bond device in TLB mode configuring
slaves' addresses], resulting in a configuration where there's a mismatch
between what's apparent to user [the netdevice's value] and what's
configured in the HW [the private value].
As we don't have any real motivation of maintaining this
private field, simply remove it and start using the netdevice's
field instead.

When management firmware declares that the device is WoL-capable,
the default driver behavior would be to allow the management firmware
to take the decision of whether it's actually needed or not.
Problem is ethtool interface doesn't have a 'default' kind
of option, and user would see the interface WoL as disabled,
which doesn't accurately reflect the actual configuration.
More-so, if the user actually wants to explicitly disable WoL he'd have
to first enable it [otherwise ethtool would block the command].
Instead of allowing management to make the decision, enable WoL by
default on all devices capable of it.

This pushes qed [and as result, all qed* drivers] into using 8.20.0.0
firmware. The changes are mostly contained in qed with minor changes
to qedi due to some HSI changes.
Content-wise, the firmware contains fixes to various issues exposed
since the release of the previous firmware, including:
- Corrects iSCSI fast retransmit when data digest is enabled.
- Stop draining packets when receiving several consecutive PFCs.
- Prevent possible assertion when consecutively opening/closing
many connections.
- Prevent possible assertion due to too long BDQ fetch time.
In addition, the new firmware would allow us to later add iWARP support
in qed and qedr.
