IPv6 uses 2 TIDs with CLIP enabled and 4 TIDs without CLIP.
Currently we are incrementing STIDs in use by 1 for both IPv4 and IPv6 which
is wrong.
Further, driver currently does not have interface to query if CLIP is programmed
for particular IPv6 address. So, in this patch we increment/decrement TIDs in use
by 4 for IPv6 assuming absence of CLIP. Such assumption keeps us on safe side and
we don't end up allocating more stids for IPv6 than actually supported.

The LE workaround code is incorrectly reusing the TCAM TIDs

We were creating LE Workaround Server Filters without specifying
IPPROTO_TCP (6) in the filters (when F_PROTOCOL is set in TP_VLAN_PRI_MAP).
This meant that UDP packets with matching IP Addresses/Ports would get
caught up in the filter and be delivered to ULDs like iw_cxgb4.
So, include the protocol information in the server filter properly.

When creating offload server entries, an IPv6 passive connection request
can trigger a reply with a null STID, whereas the driver would expect
the reply 'STID to match the value used for the request.
This happens due to h/w limitation on T4 and T5.
This patch ensures that STID 0 is never used if the stid range starts
from zero.

This version corrects the whitespace issue.
orion_mdio_wait_ready uses wait_event_timeout to wait for the
SMI interrupt to fire. wait_event_timeout waits for between
"timeout - 1" and "timeout" jiffies. In this case a 1ms timeout
when HZ is 1000 results in a wait of 0 to 1 jiffies, causing
premature timeouts.
This fix ensures a minimum timeout of 2 jiffies, ensuring
wait_event_timeout will always wait at least 1 jiffie.

but the prefix routes which did get installed by hand locally can have an

Jakub reported while working with nlmon netlink sniffer that parts of
the inet_diag_sockid are not initialized when r->idiag_family != AF_INET6.
That is, fields of r->id.idiag_src[1 ... 3], r->id.idiag_dst[1 ... 3].
In fact, it seems that we can leak 6 * sizeof(u32) byte of kernel [slab]
memory through this. At least, in udp_dump_one(), we allocate a skb in ...
rep = nlmsg_new(sizeof(struct inet_diag_msg) + ..., GFP_KERNEL);
... and then pass that to inet_sk_diag_fill() that puts the whole struct
inet_diag_msg into the skb, where we only fill out r->id.idiag_src[0],
r->id.idiag_dst[0] and leave the rest untouched:
r->id.idiag_src[0] = inet->inet_rcv_saddr;
r->id.idiag_dst[0] = inet->inet_daddr;
struct inet_diag_msg embeds struct inet_diag_sockid that is correctly /
fully filled out in IPv6 case, but for IPv4 not.
So just zero them out by using plain memset (for this little amount of
bytes it's probably not worth the extra check for idiag_family == AF_INET).
Similarly, fix also other places where we fill that out.

But using :

We get a tunnel which rejects too long packets because of the mtu check
which is not yet GSO aware.

Sockets marked with IPV6_PMTUDISC_PROBE (or later IPV6_PMTUDISC_INTERFACE)
don't respect this setting when the outgoing interface supports UFO.
We had the same problem in IPv4, which was fixed in commit
daba287b29 ("ipv4: fix DO and PROBE pmtu
mode regarding local fragmentation with UFO/CORK").
Also IPV6_DONTFRAG mode did not care about already corked data, thus
it may generate a fragmented frame even if this socket option was
specified. It also did not care about the length of the ipv6 header and
possible options.
In the error path allow the user to receive the pmtu notifications via
both, rxpmtu method or error queue. The user may opted in for both,
so deliver the notification to both error handlers (the handlers check
if the error needs to be enqueued).
Also report back consistent pmtu values when sending on an already
cork-appended socket.

Certain dm962x revisions contain an bug, where if a USB bulk transfer retry
(E.G. if bulk crc mismatch) happens right after a transfer with odd or
maxpacket length, the internal tx hardware fifo gets out of sync causing
the interface to stop working.
Work around it by adding up to 3 bytes of padding to ensure this situation
cannot trigger.
This workaround also means we never pass multiple-of-maxpacket size skb's
to usbnet, so the length adjustment to handle usbnet's padding of those can
be removed.

o Driver was using netif_tx_{stop,wake}_all_queues() api
during link change event. Remove these api calls to
manage queue start/stop event, as core networking stack
will manage this based on netif_carrier_{on,off} call.
These API's were modified as part of commit id
012ec81223 ("qlcnic: Multi Tx
queue support for 82xx Series adapter.")

The neighbour code sends up an RTM_NEWNEIGH netlink notification if
the NUD state of a neighbour cache entry is changed by a timer (e.g.
from REACHABLE to STALE), even if the lladdr of the entry has not
changed.
But an administrative change to the the NUD state of a neighbour cache
entry that does not change the lladdr (e.g. via "ip -4 neigh change
... nud ...") does not trigger a netlink notification. This means
that netlink listeners will not hear about administrative NUD state
changes such as from a resolved state to PERMANENT.
This patch changes the neighbor code to generate an RTM_NEWNEIGH
message when the NUD state of an entry is changed administratively.
