After commit e21db6f69a ("tcp: track total bytes delivered with ECN CE marks")
core TCP stack does a very good job tracking ECN signals.
The "sender's best estimate of CE information" Yuchung mentioned in his
patch is indeed the best we can do.
DCTCP can use tp->delivered_ce and tp->delivered to not duplicate the logic,
and use the existing best estimate.
This solves some problems, since current DCTCP logic does not deal with losses
and/or GRO or ack aggregation very well.
This also removes a dubious use of inet_csk(sk)->icsk_ack.rcv_mss
(this should have been tp->mss_cache), and a 64 bit divide.
Finally, we can see that the DCTCP logic, calling dctcp_update_alpha() for
every ACK could be done differently, calling it only once per RTT.

A couple of tests are verifying a route has been removed. The helper
expects the prefix as the first part of the expected output. When
checking that a route has been deleted the prefix is empty leading
to an invalid ip command:
$ ip ro ls match
Command line is not complete. Try option "help"
Fix by moving the comparison of expected output and output to a new
function that is used by both check_route and check_route6. Use the
new helper for the 2 checks on route removal.
Also, remove the reset of 'set -x' in route_setup which overrides the

When a netdev appears through hot plug then gets enslaved by a failover
master that is already up and running, the slave will be opened
right away after getting enslaved. Today there's a race that userspace
(udev) may fail to rename the slave if the kernel (net_failover)
opens the slave earlier than when the userspace rename happens.
Unlike bond or team, the primary slave of failover can't be renamed by
userspace ahead of time, since the kernel initiated auto-enslavement is
unable to, or rather, is never meant to be synchronized with the rename
request from userspace.
As the failover slave interfaces are not designed to be operated
directly by userspace apps: IP configuration, filter rules with
regard to network traffic passing and etc., should all be done on master
interface. In general, userspace apps only care about the
name of master interface, while slave names are less important as long
as admin users can see reliable names that may carry
other information describing the netdev. For e.g., they can infer that
"ens3nsby" is a standby slave of "ens3", while for a
name like "eth0" they can't tell which master it belongs to.
Historically the name of IFF_UP interface can't be changed because
there might be admin script or management software that is already
relying on such behavior and assumes that the slave name can't be
changed once UP. But failover is special: with the in-kernel
auto-enslavement mechanism, the userspace expectation for device
enumeration and bring-up order is already broken. Previously initramfs
and various userspace config tools were modified to bypass failover
slaves because of auto-enslavement and duplicate MAC address. Similarly,
in case that users care about seeing reliable slave name, the new type
of failover slaves needs to be taken care of specifically in userspace
anyway.
It's less risky to lift up the rename restriction on failover slave
which is already UP. Although it's possible this change may potentially
break userspace component (most likely configuration scripts or
management software) that assumes slave name can't be changed while
UP, it's relatively a limited and controllable set among all userspace
components, which can be fixed specifically to listen for the rename
events on failover slaves. Userspace component interacting with slaves
is expected to be changed to operate on failover master interface
instead, as the failover slave is dynamic in nature which may come and
go at any point. The goal is to make the role of failover slaves less
relevant, and userspace components should only deal with failover master
in the long run.

stack overflow on kfree_skb() (which is called recursively on
the frag_lists).

various workqueues throughout the kernel [2][3][4] in order to silence

These patches do the same for the workqueues created by mlxsw that

In Spectrum-1, when a multicast packet is admitted to the shared buffer
it increases the quotas of all the ports and {port, TC} to which it is
forwarded to.
The above means that multicast packets are accounted multiple times in
the shared buffer and can therefore cause the associated shared buffer
pool to fill up very quickly.
To work around this issue, commit e83c045e53 ("mlxsw:
spectrum_buffers: Configure MC pool") added a dedicated multicast pool
in which multicast packets are accounted.
The issue is not present in Spectrum-2, but in order to be backward
compatible with Spectrum-1, its default behavior is to allow a multicast
packet to increase multiple egress quotas instead of one.
Until the new (non-backward compatible) mode is supported, configure a
dedicated multicast pool as in Spectrum-1.

The workqueue is used to periodically update the networking stack about
activity / statistics of various objects such as neighbours and TC
actions.
It should not be called as part of memory reclaim path, so remove the
WQ_MEM_RECLAIM flag.

The EMAD workqueue is used to handle retransmission of EMAD packets that
contain configuration data for the device's firmware.
Given the workers need to allocate these packets and that the code is
not called as part of memory reclaim path, remove the WQ_MEM_RECLAIM
flag.

Restore SW_CRYPTO_CONTROL operation on AP_VLAN interfaces for unicast
keys, the original override was intended to be done for group keys as
those are treated specially by mac80211 and would always have been
rejected.
Now the situation is that AP_VLAN support must be enabled by the driver
if it can support it (meaning it can support software crypto GTK TX).
Thus, also simplify the code - if we get here with AP_VLAN and non-
pairwise key, software crypto must be used (driver doesn't know about
the interface) and can be used (driver must've advertised AP_VLAN if
it also uses SW_CRYPTO_CONTROL).

bnxt_en: 2 bug fixes.
The first patch prevents possible driver crash if we get a bad RX index
from the hardware. The second patch resets the device when the hardware
reports buffer error to recover from the error.
Please queue these for -stable also. Thanks.
