Intel Wired LAN Driver Updates 2015-03-03
This series contains updates to fm10k, i40e and i40evf.
Matthew updates the fm10k driver by cleaning up code comments and whitespace
issues. Also modifies the tunnel length header check, to make it more robust
by calculating the inner L4 header length based on whether it is TCP or UDP.
Implemented ndo_features_check() that allows drivers to report their offload
capabilities per-skb.
Neerav updates the i40e driver to skip over priority tagging if DCB is not
enabled. Fixes an issue where the driver is not flushing out the
DCBNL app table for applications that are not present in the local DCBX
application configuration TLVs. Fixed i40e where, in the case of MFP
mode, the driver was returning the incorrect number of traffic classes
for partitions that are not enabled for iSCSI. Even though the driver
was not configuring these traffic classes in the transmit scheduler for
the NIC partitions, it does use this map to setup the queue mappings.
Shannon updates i40e/i40evf to include the firmware build number in the
formatted firmware version string.
Akeem adds a safety net (by adding a 'default' case) for the possible
unmatched switch calls.
Mitch updates i40e to not automatically disable PF loopback at runtime,
now that we have the functionality to enable and disable PF loopback. This
fix cleans up a bogus error message when removing the PF module with VFs
enabled. Adds a extra check to make sure that the indirection table
pointer is valid before dereferencing it.
Anjali enables i40e to enable more than the max RSS qps when running in a
single TC mode for the main VSI. It is possible to enable as many as
num_online_cpus(). Adds a firmware check to ensure that DCB is disabled for
firmware versions older than 4.33. Updates i40e/i40evf to add missing
packet types for VXLAN offload. Updated i40e to be able to handle varying
RSS table size for each VSI, since all VSI's do not have the same RSS table
size.
v2: Dropped previous patch #9 "i40e/i40evf: Add capability to gather VEB
per TC stats" since the stats should be in ethtool and not debugfs.

Before the ax25 stack calls dev_queue_xmit it always calls
ax25_type_trans which sets skb->protocol to ETH_P_AX25.
Which means that by looking at the protocol type it is possible to
detect IP packets that have not been munged by the ax25 stack in
ndo_start_xmit and call a function to munge them.
Rename ax25_neigh_xmit to ax25_ip_xmit and tweak the return type and
value to be appropriate for an ndo_start_xmit function.
Update all of the ax25 devices to test the protocol type for ETH_P_IP
and return ax25_ip_xmit as the first thing they do. This preserves
the existing semantics of IP packet processing, but the timing will be
a little different as the IP packets now pass through the qdisc layer
before reaching the ax25 ip packet processing.
Remove the now unnecessary ax25 neighbour table operations.

In case of MFP mode the driver was returning incorrect number of TCs
for partitions that are not enabled for iSCSI. Though the driver does
not configure these TCs in the Tx scheduler for the NIC partitions;
it does use this map to setup the queue mappings.
This patch fixes this and keeps all the NIC partitions to the default
PF TC i.e. TC0.

With changes to default number of queue pairs that the interface comes up with
from 1 per online CPU to 1 per lan_msix, we need to make sure we recalculate
rss_size. We will now recalculate rss_size based on number of queues enabled in
the VSI.
Without this fix if the max_lan_msix < num_online_cpu we will be coming up
with fewer queues but will be populating rss_size based on num_online_cpus.
This will result in packets getting silently dropped because RSS LUT has queues
that are not enabled.

Include the FW build number in the formatted FW version string. In order
to fit within ethtool's 32 character limit, the etrack's unused high order
bits are trimmed as is the leading 0 for the NVM version. This leaves
us with 2 character left for if/when the etrack id goes to 5 hex chars
and the NVM major number goes to 2 chars.

The FM10000 host interface can only support up to 184 bytes when
performing tunnel offloads. Because of this, a check was added to
prevent the driver from attempting to feed a header to the hardware too
big for it to parse. Make this check a little more robust by calculating
the inner L4 header length based on whether it is TCP or UDP.

====================
Neighbour table and ax25 cleanups
While looking at the neighbour table to what it would take to allow
using next hops in a different address family than the current packets
I found a partial resolution for my issues and I stumbled upon some
work that makes the neighbour table code easier to understand and
maintain.
Long ago in a much younger kernel ax25 found a hack to use
dev_rebuild_header to transmit it's packets instead of going through
what today is ndo_start_xmit.
When the neighbour table was rewritten into it's current form the ax25
code was such a challenge that arp_broken_ops appeard in arp.c and
neigh_compat_output appeared in neighbour.c to keep the ax25 hack alive.
With a little bit of work I was able to remove some of the hack that
is the ax25 transmit path for ip packets and to isolate what remains
into a slightly more readable piece of code in ax25_ip.c. Removing the
need for the generic code to worry about ax25 special cases.
After cleaning up the old ax25 hacks I also performed a little bit of
work on neigh_resolve_output to remove the need for a dst entry and to
ensure cached headers get a deterministic protocol value in their cached
header. This guarantees that a cached header will not be different
depending on which protocol of packet is transmitted, and it allows
packets to be transmitted that don't have a dst entry. There remains
a small amount of code that takes advantage of when packets have a dst
entry but that is something different.

Having a dst helps a little bit for teql but is fundamentally
unnecessary and there are code paths where a dst is not available that
it would be nice to use the neighbour cache.

- Add protocol to neigh_tbl so that dst->ops->protocol is not needed
- Acquire the device from neigh->dev
This results in a neigh_hh_init that will cache the samve values

Have ax25_neigh_output perform ordinary arp resolution before calling
ax25_neigh_xmit.
Call dev_hard_header in ax25_neigh_output with a destination address so
it will not fail, and the destination mac address will not need to be
set in ax25_neigh_xmit.
Remove arp_find from ax25_neigh_xmit (the ordinary arp resolution added
to ax25_neigh_output removes the need for calling arp_find).
Document how close ax25_neigh_output is to neigh_resolve_output.

Not setting the destination address is a bug that I suspect causes no
problems today, as only the arp code seems to call dev_hard_header and
the description I have of rose is that it is expected to be used with a
static neigbour table.
I have derived the offset and the length of the rose destination address
from rose_rebuild_header where arp_find calls neigh_ha_snapshot to set
the destination address.
