There is a maximum TX burst size that the ENA device can handle.
It is exposed by the device to the driver and the driver
needs to comply with it to avoid bugs.
In this commit we:
1. Add ena_com_is_doorbell_needed(), which calculates the number of
llq entries that will be used to hold a packet, and will return
true if they exceed the number of allowed entries in a burst.
If the function returns true, a doorbell needs to be invoked
to send this packet in the next burst.
2. Follow the available entries in the current burst:
- Every doorbell a new burst begins
- With each write of an llq entry, the available entries in the
current burst are decreased by 1.

====================
isdn: deprecate non-mISDN drivers
When isdn4linux came up in the context of another patch series, I
remembered that we had discussed removing it a while ago.
It turns out that the suggestion from Karsten Keil wa to remove I4L
in 2018 after the last public ISDN networks are shut down. This has
happened now (with a very small number of exceptions), so I guess it's
time to try again.
We currently have three ISDN stacks in the kernel: the original
isdn4linux (with the hisax driver), the newer CAPI (with four drivers),
and finally the mISDN stack (supporting roughly the same hardware as
hisax).
As far as I can tell, anyone using ISDN with mainline kernel drivers in
the past few years uses mISDN, and this is typically used for voice-only
PBX installations that don't require a public network.
The older stacks support additional features for data networks, but those
typically make no sense any more if there is no network to connect to.
My proposal for this time is to kill off isdn4linux entirely, as it seems
to have been unusable for quite a while. This code has been abandoned
for many years and it does cause problems for treewide maintenance as
it tends to do everything that we try to stop doing.
Birger Harzenetter mentioned that is is still using i4l in order to
make use of the 'divert' feature that is not part of mISDN, but has
otherwise moved on to mISDN for normal operation, like apparently
everyone else.
CAPI in turn is not quite as obsolete, but two of the drivers (avm
and hysdn) don't seem to be used at all, while another one (gigaset)
will stop being maintained as Paul Bolle is no longer able to
test it after the network gets shut down in September.
All three are now moved into drivers/staging to let others speak
up in case there are remaining users.
This leaves Bluetooth CMTP as the only remaining user of CAPI, but
Marcel Holtmann wishes to keep maintaining it.
For the discussion on version 1, see [2]
Unfortunately, Karsten Keil as the maintainer has not participated in
the discussion.

Aleksandr modifies the driver to limit the number of RSS queues to the

Gustavo A. R. Silva converts a couple of instances where sizeof() can be

Alice makes the remaining changes to the iavf driver to cleanup all the
old "i40evf" references in the driver to iavf, including the file names
that still contained the old driver reference. There was no functional
changes made, just cosmetic to reduce any confusion going forward now
that the iavf driver is the virtual function driver for both i40e and

I tried to find any indication of whether the capi drivers are still in
use, and have not found anything from a long time ago.
With public ISDN networks almost completely shut down over the past 12
months, there is very little you can actually do with this hardware. The
main remaining use case would be to connect ISDN voice phones to an
in-house installation with Asterisk or LCR, but anyone trying this in
turn seems to be using either the mISDN driver stack, or out-of-tree
drivers from the hardware vendors.
I may of course have missed something, so I would suggest moving these
three drivers (avm, hysdn, gigaset) into drivers/staging/ just in case
someone still uses them.
If nobody complains, we can remove them entirely in six months, or
otherwise move the core code and any drivers that are still needed back
into drivers/isdn.
As Paul Bolle notes, he is still testing the gigaset driver as long as
he can, but the Dutch ISDN network will be shut down in September 2019,
which puts an end to that.
Marcel Holtmann still maintains the Bluetooth CMTP profile and wants to
keep that alive, so the actual CAPI subsystem code remains in place for
now, after all other drivers are gone, CMTP and CAPI can be merged into
a single driver directory.

With all isdn4linux hardware drivers gone, this is only a wrapper around
CAPI to support old user space. However, from looking at the mailing
list, it seems that the last time anyone asked about it was in 2014,
when the upgrade from a linux-2.4 installation failed, and mISDN was
suggested as a replacement.
The largest public ISDN network (Deutsche Telekom) was supposed to be
shut down 2018, which must have drastically reduced the number of legacy
installations.
When we last discussed removing i4l in 2016, Karsten Keil suggested
revisiting this in 2018. I guess this is overdue.

With the decline of ISDN, this seems to have become almost completely
obsolete, and even in the past years before that, almost all remaining
users appear to have used mISDN instead.
Birger Harzenetter noted that he is still using i4l/hisax to take
advantage of the 'divert' driver for call diversion, but otherwise uses
mISDN on the same hardware. This is a rare edge case as far as I
can tell, but we are still breaking an actively used work flow
(see https://xkcd.com/1172/).
We debated moving i4l/hisax to staging as an intermediate step, but as
he is not likely to change the setup, and that would just delay breaking
this use case. The alternatives here are to stay on stable kernels
< 5.2, to create an external driver repository for isdn4linux, or to
add divert functionality to mISDN.

1 warning generated.
We can convert from gnu_printf to printf without any side effects for
two reasons:
1. All iavf_debug instances use standard printf formats, as pointed out
by Miguel Ojeda at the below link, meaning gnu_printf is not strictly
required.
2. However, GCC has aliased printf to gnu_printf on Linux since at least
2010 based on git history.
From gcc/c-family/c-format.c:
/* Attributes such as "printf" are equivalent to those such as
"gnu_printf" unless this is overridden by a target. */
static const target_ovr_attr gnu_target_overrides_format_attributes[] =
{
{ "gnu_printf", "printf" },
{ "gnu_scanf", "scanf" },
{ "gnu_strftime", "strftime" },
{ "gnu_strfmon", "strfmon" },
{ NULL, NULL }
};
The mentioned override only happens on Windows (mingw32). Changing from
gnu_printf to printf is a no-op for GCC and stops Clang from warning.

100GbE Intel Wired LAN Driver Updates 2019-05-30
This series contains updates to ice driver only.
Brett continues his work with interrupt handling by fixing an issue
where were writing to the incorrect register to disable all VF
interrupts.
Tony consolidates the unicast and multicast MAC filters into a single
new function.
Anirudh adds support for virtual channel vector mapping to receive and
transmit queues. This uses a bitmap to associate indicated queues with
the specified vector. Makes several cosmetic code cleanups, as well as
update the driver to align with the current specification for managing
MAC operation codes (opcodes).
Paul adds support for Forward Error Correction (FEC) and also adds the
ethtool get and set handlers to modify FEC parameters.
Bruce cleans up the driver code to fix a number of issues, such as,
reducing the scope of some local variables, reduce the number of
de-references by changing a local variable and reorder the code to
remove unnecessary "goto's".
Dave adds switch rules to be able to handle LLDP packets and in the
process, fix a couple of issues found, like stop treating DCBx state of
"not started" as an error and stop hard coding the filter information
flag to transmit.
Jacob updates the driver to allow for more granular debugging by
developers by using a distinct separate bit for dumping firmware logs.

This patch is a step towards allowing PHY drivers to handle more
interrupt sources than just link change. E.g. several PHY's have
built-in temperature monitoring and can raise an interrupt if a
temperature threshold is exceeded. We may be interested in such
interrupts also if the phylib state machine isn't started.
Therefore move enabling interrupts to phy_request_interrupt().

This patch is a further step towards decoupling firmware handling from
the actual driver code. Firmware can be for PHY and/or MAC, and two
pairs of read/write functions are needed for handling PHY firmware and
MAC firmware respectively. Pass these functions via struct rtl_fw and
avoid the ugly switching of mdio_ops behind the back of rtl_writephy().

Call the pll power down function also for chip versions 02..06 and
13..15. The MAC can't be powered down on these chip versions, but at
least they benefit from the speed-down power-saving if WoL is enabled.
