This NIC doesn't have hardware IRQ coalescing. Under high load,
interrupts can adversely affect performance. To mitigate this, enable
software IRQ coalescing by default. On my system this increases receive
throughput with iperf3 from 853 MBit/sec to 934 MBit/s, decreases
interrupts from 69489/sec to 2016/sec, and decreases CPU utilization
from 27% (4x Cortex-A53) to 14%. Latency is not affected (as far as I
can tell).

When reading registers from the PHY using the SIOCGMIIREG IOCTL any
errors returned from either mdiobus_read() or mdiobus_c45_read() are
ignored, and parts of the returned error is passed as the register value
back to user-space.
For example, if mdiobus_c45_read() is used with a bus that do not
implement the read_c45() callback -EOPNOTSUPP is returned. This is
however directly stored in mii_data->val_out and returned as the
registers content. As val_out is a u16 the error code is truncated and
returned as a plausible register value.
Fix this by first checking the return value for errors before returning
it as the register content.
Before this patch,
# phytool read eth0/0:1/0
0xffa1
After this change,
$ phytool read eth0/0:1/0
error: phy_read (-95)

Replace comma between expressions with semicolons.
Using a ',' in place of a ';' can have unintended side effects.

RT_TOS() from include/uapi/linux/in_route.h is defined using
IPTOS_TOS_MASK from include/uapi/linux/ip.h. This is problematic for
files such as include/net/ip_fib.h that want to use RT_TOS() as without
including both header files kernel compilation fails:
In file included from ./include/net/ip_fib.h:25,
from ./include/net/route.h:27,
from ./include/net/lwtunnel.h:9,
from net/core/dst.c:24:

Therefore, cited commit changed linux/in_route.h to include linux/ip.h.
However, as reported by David, this breaks iproute2 compilation due
overlapping definitions between linux/ip.h and
/usr/include/netinet/ip.h:

Fix by changing include/net/ip_fib.h to include linux/ip.h. Note that

Commit aa92c1cec92b ("l2tp: add tunnel/session get_next helpers") uses
idr_get_next APIs to iterate over l2tp session IDR lists. Sessions in
l2tp_v2_session_idr always have a non-null session->tunnel pointer
since l2tp_session_register sets it before inserting the session into
the IDR. Therefore the null check on session->tunnel in
l2tp_v2_session_get_next is redundant and can be removed. Removing the
check avoids a warning from lkp.

Add support for group stats for mac. The fbnic_set_counter help preserve
the default values for counters which are not touched by the driver.
The 'reset' flag in 'get_eth_mac_stats' allows to choose between
resetting the counter to recent most value or fetching the aggregated
values of the counter.
The 'fbnic_stat_rd64' read 64b stats counters in an atomic fashion using
read-read-read approach. This allows to isolate cases where counter is
moving too fast making accuracy of the counter questionable.

Currently, the driver uses a linked list for storing the tx buffer
addresses. This requires a good amount of extra bookkeeping code. Ditch
the linked list in favor of tx buffers being in the same contiguous
memory space as the DCB's and the DB's. The FDMA library has a helper
for this - so use that.
The tx buffer addresses are now retrieved as an offset into the FDMA
memory space.

dev_err_probe()"
This reverts commit bf4d87f884fe8a4b6b61fe4d0e05f293d08df61c because it
introduced dev_err_probe() in non-probe path, which is not desired.
In general, calling dev_err_probe() after successful probe in case of
handling -EPROBE_DEFER error, will set deferred status on the device
already probed. This is however not a problem here now, because
dev_err_probe() in affected places is used for handling errors from
request_firmware(), which does not return -EPROBE_DEFER. Still usage of
dev_err_probe() in such case is not correct, because request_firmware()
could once return -EPROBE_DEFER.

Default ruleset uses fib, reject and objref expressions which were
missing.
Other missing expressions can be added later.
Improve decoding while at it:
- add bitwise, ct and lookup attributes
- wire up the quota expression
- translate raw verdict codes to a human reable name, e.g.
'code': 4294967293 becomes 'code': 'jump'.

Instead of displaying 'invert' when looking at some events like MP_FAIL,
MP_FASTCLOSE, MP_RESET, RM_ADDR, which is a bit vague because they are
not traditionnaly sent from one side, the host being checked is now
printed.
For the ADD_ADDR, only display the host when it is the client sending
it, which is more unusual.
Also before, the 'invert' message was printed after a few checks, but it
was not clear which ones exactly.

Before, the check names had to be very short. It is no longer the case
now that these checks are printed on a dedicated line.
Then, it looks better to have more explicit names.

A few new MPJoinSynTx MIB counters have been added in a previous commit.
They are being validated here in mptcp_join.sh selftest, each time the
number of received MPJ are checked.
Most of the time, the number of sent SYN+MPJ is the same as the received
ones. But sometimes, there are more, because there are dropped, or there
are errors.
While at it, the "no MPC reuse with single endpoint" subtest has been
modified to force a bind() error.

Most tests are checking if the expected number of SYN/SYN+ACK/ACK JOINs
have been received, each of them on one line.
More Join related tests are going to be checked soon, no need to add 5
new lines per test in case of success, just one is enough. In case of
issue, the errors will still be reported like before.

chk_join_nr() currently takes 9 positional parameters, 6 of them are
optional. It makes it hard to read:
chk_join_nr 1 1 1 1 0 1 1 0 4
Naming these vars helps to make it easier to read:
join_csum_ns1=1 join_csum_ns2=0 \
join_fail_nr=1 join_rst_nr=1 join_infi_nr=0 \
join_corrupted_pkts=4 \
chk_join_nr 1 1 1
It will then be easier to add new optional parameters.

Recently, a few issues have been discovered around the creation of
additional subflows. Without these counters, it was difficult to point
out the reason why some subflows were not created as expected.
These counters should have been added earlier, because there is no other
simple ways to extract such information from the kernel, and understand
why subflows have not been created.
While at it, some pr_debug() have been added, just in case the errno
needs to be printed.

__mptcp_subflow_connect() is currently called from the path-managers,
which have all the required information to create subflows. No need to
call the PM again to re-iterate over the list of entries with RCU lock
to get more info.
Instead, it is possible to pass a mptcp_pm_addr_entry structure, instead
of a mptcp_addr_info one. The former contains the ifindex and the flags
that are required when creating the new subflow.
This is a partial revert of commit ee285257a9c1 ("mptcp: drop flags and
ifindex arguments").
While at it, the local ID can also be set if it is known and 0, to avoid
having to set it in the 'rebuild_header' hook, which will cause a new
iteration of the endpoint entries.

Rename all the helpers specific to the flushing operations to make it
clear that the intention is to flush all created subflows, and remove
all announced addresses, not just a specific selection.
That way, it is easier to understand why the id_avail_bitmap and
local_addr_used are reset at the end.
