With commit 2d55173e71b0 ("phy: add generic function to support
ksetting support"), we lost the ability to report the transceiver type
like we used to. Now that we have added back the transceiver type to
ethtool_link_settings, we can report it back like we used to and have no
loss of information.

The EMAC has the option of sending only a single pause frame when
flow control is enabled and the RX queue is full. Although sending
only one pause frame has little value, this would allow admins to
enable automatic flow control without having to worry about the EMAC
flooding nearby switches with pause frames if the kernel hangs.
The option is enabled by using the single-pause-mode private flag.

If MTU is changed the host would reject the send buffer change.
This problem is result of recent change to allow changing send
buffer size.
Every time we change the MTU, we store the previous net_device section
count before destroying the buffer, but we don’t store the previous
section size. When we reinitialize the buffer, its size is calculated
by multiplying the previous count and previous size. Since we
continuously increase the MTU, the host returns us a decreasing count
value while the section size is reinitialized to 1728 bytes every
time.
This eventually leads to a condition where the calculated buf_size is
so small that the host rejects it.

rss_size is 1, 2, 4, 8, 16, 32, 64, 128, but acutal tc queue
size can be any u16 less than 128. If tc queue size is 5, we
set the rss_size to 8, indirection table will be used to limit
the size of actual queue size.
It may cause dropping of receiving packet in hardware if
rss_size is not set correctly.
For now, each TC has the same rss size.

rx_priv_buf_alloc is used to tell hardware how much buffer is
used for rx direction, right now only the private buffer is
assigned.
For ae_dev that doesn't support DCB, private rx buffer is assigned
to zero, only shared rx buffer is used. So not setting the shared

This patch is pretty much a carbon copy of
commit 3079c652141f ("caif: Fix napi poll list corruption")
with "caif" replaced by "emac".
The commit d75b1ade567f ("net: less interrupt masking in NAPI")
breaks emac.
It is now required that if the entire budget is consumed when poll
returns, the napi poll_list must remain empty. However, like some
other drivers emac tries to do a last-ditch check and if there is
more work it will call napi_reschedule and then immediately process
some of this new work. Should the entire budget be consumed while
processing such new work then we will violate the new caller
contract.
This patch fixes this by not touching any work when we reschedule
in emac.

There are several problems with commit 10377ba7673d ("net: systemport:
Support 64bit statistics", first one got fixed in 7095c973453e ("net:
systemport: Fix 64-bit stats deadlock").
The second problem is that this specific code updates the
stats64.tx_{packets,bytes} from ndo_get_stats64() and that is what we
are returning to ethtool -S. If we are not running a tool that involves
calling ndo_get_stats64(), then we won't get updated ethtool stats.
The solution to this is to update the stats from both call sites,
factoring that into a specific function, While at it, don't just check
the sizeof() but also the type of the statistics in order to use the
64-bit stats seqlock.

If the network interface is kept running during suspend, the net core
may call net_device_ops.ndo_start_xmit() while the Ethernet device is
still suspended, which may lead to a system crash.
E.g. on sh73a0/kzm9g and r8a73a4/ape6evm, the external Ethernet chip is
driven by a PM controlled clock. If the Ethernet registers are accessed
while the clock is not running, the system will crash with an imprecise
external abort.
As this is a race condition with a small time window, it is not so easy
to trigger at will. Using pm_test may increase your chances:
# echo 0 > /sys/module/printk/parameters/console_suspend
# echo platform > /sys/power/pm_test
# echo mem > /sys/power/state
To fix this, make sure the network interface is quietened during
suspend.

drivers/net/vrf.c: In function ‘vrf_ip6_input_dst’:
drivers/net/vrf.c:964:3: error: initialized field with side-effects overwritten [-Werror]
drivers/net/vrf.c:964:3: error: (near initialization for ‘fl6’) [-Werror]
I have no idea what this warning is even trying to say, but it does
seem like a false positive. Reordering the initialization in to match
the structure definition gets rid of the warning, and might also avoid
whatever gcc thinks is wrong here.

call to memset to assign 0 value immediately after allocating
memory with kzalloc is unnecesaary as kzalloc allocates the memory
filled with 0 value.
Semantic patch used to resolve this issue:
@@
expression e,e2; constant c;
statement S;
@@
e = kzalloc(e2, c);
if(e == NULL) S
- memset(e, 0, e2);

tnapi is being initialized and then immediately updated and
hence the initialiation is redundant. Clean up the warning
by moving the declaration and initialization to the inside
of the for-loop.
Cleans up clang scan-build warning:
warning: Value stored to 'tnapi' during its initialization is never read

... and __initconst if applicable.
Based on similar work for an older kernel in the Grsecurity patch.

The control process (NSP) may take some time to complete its
initialization. This is not a problem on most servers, but
on very fast-booting machines it may not be ready for operation
when driver probes the device. There is also a version of the
flash in the wild where NSP tries to train the links as part
of init. To wait for NSP initialization we should make sure
its resource has already been added to the resource table.
NSP adds itself there as last step of init.

Board state informs us which low-level initialization stages the card
has completed. We should wait for the card to be fully initialized
before trying to communicate with it, not only before we configure
passing traffic.

Previously we did not check the flow dissector against a list of allowed
and supported flow key dissectors. This patch introduces such a list and
correctly rejects unsupported flow keys.

IPv6 TSO requests with extension hdrs are a problem to the
Lancer and BEx chips. Workaround is to disable TSO6 feature
for such packets.
Also in Lancer chips, MSS less than 256 was resulting in TX stall.
Fix this by disabling GSO when MSS less than 256.

A randconfig build caused a compile failure:
drivers/net/ethernet/nuvoton/w90p910_ether.c: In function 'w90p910_ether_close':
drivers/net/ethernet/nuvoton/w90p910_ether.c:580:2: error: implicit declaration of function 'free_irq'; did you mean 'free_uid'? [-Werror=implicit-function-declaration]
Adding the correct include fixes the problem.
