messages don't easily get associated to the actual request. Here
we add a bit of information to the error messages to help

Remove the need for a reset when the device enters limited promiscuous
mode. This was causing heartburn for people who were using VFs and
bridging, since this would require all of the VFs to undergo a reset
each time the PF changed its promiscuity.

Always add MAC address at the tail of the MAC filter list. Since the
device's "real" MAC address is added first, it will always be at the
beginning of the list. This prevents an issue where the "real" MAC
filter might not get added if too many other filters are added before
bringing the interface up.

Limiting qcount to pf->num_lan_msix, effectively limits the RSS queues
to only use the number of CPUs, and ignore all other queues. We don't
want to do this. If the user has changed the RSS settings to use more
queues then CPUS, we want to trust they know what they are doing and
let them. More importantly, if we tell them that is what we did, we want
to actually do it and allow traffic into all of the queues we have
allocated. This does not change the default setting to initially
allocate only the number of CPUS of queue pairs.

If the user adds an obscene amount of MAC addresses, the driver will run
into the situation where it has too many address requests to fit into a
single PF message. The driver checks for this case, and calculates the
maximum number of messages that it can send. Then it completely ignores
this count and overflows the buffer.
Fix this by checking the address count and bailing out of the loop at
the appropriate time.

There is no prevention of a concurrent call to both fixed_mdio_read()
and fixed_phy_update_state(), which can result in the state being
modified while it's being inspected. Fix this by using a seqcount
to detect modifications, and memcpy()ing the state.
We remain slightly naughty here, calling link_update() and updating
the link status within the read-side loop - which would need rework
of the design to change.

However device match is not enforced in table lookup, so the found

In "NFSv4: Move dentry instantiation into the NFSv4-specific atomic open code"
unconditional d_drop() after the ->open_context() had been removed. It had
been correct for success cases (there ->open_context() itself had been doing
dcache manipulations), but not for error ones. Only one of those (ENOENT)
got a compensatory d_drop() added in that commit, but in fact it should've
been done for all errors. As it is, the case of O_CREAT non-exclusive open
on a hashed negative dentry racing with e.g. symlink creation from another
client ended up with ->open_context() getting an error and proceeding to
call nfs_lookup(). On a hashed dentry, which would've instantly triggered
BUG_ON() in d_materialise_unique() (or, these days, its equivalent in
d_splice_alias()).

In this mode the moderation timer will restart upon
new completion (CQE) generation rather than upon interrupt
generation.
The outcome is that for bursty traffic the period timer will never
expire and thus only the moderation frames counter will dictate
interrupt generation, thus the interrupt rate will be relative
to the incoming packets size.
If the burst seizes for "moderation period" time then an interrupt
will be issued immediately.
CQE based moderation is off by default and can be controlled
via ethtool set_priv_flags.

Later a Send Queue uses this index to set the rate limit.
Multiple Send Queues can have the same rate limit, which is
represented by a single entry in this table.
Even though a rate can be shared, each queue is being rate
limited independently of others.
The SW shadow of this table holds the rate itself,
the index in the HW table and the refcount (number of queues)

On SR-IOV profiles, when the user connects a Linux Bridge or OVS to a BE3
vport, they suffer the "broadcast/multicast echo" problem. BE3 EVB echoes
broadcast and multicast packets back to PF's vport confusing the
Linux bridge. BE3 relies on the src-mac addr being programmed on the
interface to avoid sending back an echo of a broadcast or multicast packet
on a vPort. When a Linux bridge is connected to a BE3, the mac-addr of the
VM behind the bridge doesn't get configured on the vPort and so echo
cancellation doesn't work.
This patch worksaround this problem by disabling the EVB initially
and re-enabling it *only* when SR-IOV is enabled by the user. For the
driver fix to work, the BE3 FW version must be >= 11.1.84.0.

be2net so far supported creation of RX/TX queues only in pairs.
On configs where rx and tx queue counts are different, creation of only
the lesser number of queues has been supported.
This patch now allows a combination of RX/TX-only channels along with
combined channels. N TX-queues and M RX-queues can be created with the
following cmds:
ethtool -L ethX combined N rx M-N (when N < M)
ethtool -L ethX combined M tx N-M (when M < N)
Setting both RX-only and TX-only channels is still not supported.
It is mandatory to create atleast one combined channel.

The EQs available on a function are shared between NIC and RoCE.
The be_max_eqs() macro was so far being used to refer to the max number of
EQs available for NIC. This has caused some confusion in the code. To fix
this confusion this patch introduces a new macro called be_max_nic_eqs()
to refer to the max number of EQs avialable for NIC only and renames
be_max_eqs() to be_max_func_eqs().

Andy Duan says:
====================
net: fec: add new type device
Different i.MX SOC FEC support different features like :
- i.MX6Q/DL FEC does not support AVB and interrupt coalesc
- i.MX6SX/i.MX7D supports AVB and interrupt coalesc
- i.MX6UL/ULL does not support AVB, but support interrupt coalesc
Then, add new quirk flag to judge the supported features, and add new
type device for i.MX6UL.
