bdfa4ed681 r8169: use Giant Send
Replace large send with giant send for TSO for RTL8111C and later ICs.
The large send setting of the RTL8111DP is different from the other
chips. However, the giant send setting is the same for all the chips
which support it. Use the giant send to synchronize the settings.

7ad24ea4bf net: get rid of SET_ETHTOOL_OPS
net: get rid of SET_ETHTOOL_OPS

Dave Miller mentioned he'd like to see SET_ETHTOOL_OPS gone.
This does that.

Mostly done via coccinelle script:
@@
struct ethtool_ops *ops;
struct net_device *dev;
@@
-       SET_ETHTOOL_OPS(dev, ops);
+       dev->ethtool_ops = ops;

Compile tested only, but I'd seriously wonder if this broke anything.

57a7744e09 net: Replace u64_stats_fetch_begin_bh to u64_stats_fetch_begin_irq
Replace the bh safe variant with the hard irq safe variant.

We need a hard irq safe variant to deal with netpoll transmitting
packets from hard irq context, and we need it in most if not all of
the places using the bh safe variant.

Except on 32bit uni-processor the code is exactly the same so don't
bother with a bh variant, just have a hard irq safe variant that
everyone can use.

50ff44be40 8139cp: Don't receive packets when the napi budget == 0
Processing any incoming packets with a with a napi budget of 0
is incorrect driver behavior.

This matters as netpoll will shortly call drivers with a budget of 0
to avoid receive packet processing happening in hard irq context.

These are occuring because the seqcount embedded in u64_stats_sync on

------------[ cut here ]------------

When a skb has frags, bytes_compl plus skb->len nr_frags times in cp_tx().
It's not the correct value(actually, it should plus skb->len once) and it
will trigger the BUG_ON(bytes_compl > num_queued - dql->num_completed).
So only increase bytes_compl when finish sending all frags. pkts_compl also
has a wrong value, fix it too.

It's introduced by commit 871f0d4c ("8139cp: enable bql").

1bac107242 r8169: check ALDPS bit and disable it if enabled for the 8168g
Windows driver will enable ALDPS function, but linux driver and firmware
do not have any configuration related to ALDPS function for 8168g.
So restart system to linux and remove the NIC cable, LAN enter ALDPS,
then LAN RX will be disabled.

This issue can be easily reproduced on dual boot windows and linux
system with RTL_GIGA_MAC_VER_40 chip.

Realtek said, ALDPS function can be disabled by configuring to PHY,
switch to page 0x0A43, reg0x10 bit2=0.

827da44c61 net: Explicitly initialize u64_stats_sync structures for lockdep
In order to enable lockdep on seqcount/seqlock structures, we
must explicitly initialize any locks.

The u64_stats_sync structure, uses a seqcount, and thus we need
to introduce a u64_stats_init() function and use it to initialize
the structure.

This unfortunately adds a lot of fairly trivial initialization code
to a number of drivers. But the benefit of ensuring correctness makes
this worth while.

Because these changes are required for lockdep to be enabled, and the
changes are quite trivial, I've not yet split this patch out into 30-some
separate patches, as I figured it would be better to get the various
maintainers thoughts on how to best merge this change along with
the seqcount lockdep enablement.

Feedback would be appreciated!

Config5. This is necessary to preserve WOL state when the driver is
loaded. Although the r8168 vendor driver does not write Config5 (it has
been commented out), Hayes Wang from Realtek said that masking bits like
this is more sensible.

e7fb06a1b4 r8169,sis190: remove unnecessary length check
The ethtool core will lower the requested length to the one returned by
get_regs_len, therefore no additional check is needed in the get_regs

link handling and phy reset rework) and is printed every ten seconds
when no cable is connected and runtime power management is disabled.
(Before that commit, "Reset RTL8169s PHY" would be printed instead.)

cf3c4c0306 8139cp: Add dma_mapping_error checking
Self explanitory dma_mapping_error addition to the 8139 driver, based on this:
https://bugzilla.redhat.com/show_bug.cgi?id=947250

It showed several backtraces arising for dma_map_* usage without checking the
return code on the mapping.  Add the check and abort the rx/tx operation if its
failed.  Untested as I have no hardware and the reporter has wandered off, but
seems pretty straightforward.

4ea72445bd r8169: fix lockdep warning when removing interface
The work queue is initialised in rtl_open (when the interface goes up),
but canceled in rtl_remove_one (when the PCI device gets removed). If
the network interface is not brought up, then the work queue struct is
not initialised. When the device is removed, the attempt to cancel the
uninitialised work queue causes a lockdep warning.

This patch fixes the issue by moving cancel_work_sync to rtl_close (to
match rtl_open). (Note that rtl_close is also called via
unregister_netdev in rtl_remove_one.)

All drivers that select MII also need to select NET_CORE because MII

There is also no need for it to be a visible option, since its users

b423e9ae49 r8169: fix offloaded tx checksum for small packets.
8168evl offloaded checksums are wrong since commit
e5195c1f31 ("r8169: fix 8168evl frame padding.")
pads small packets to 60 bytes (without ethernet checksum). Typical symptoms
appear as UDP checksums which are wrong by the count of added bytes.

It isn't worth compensating. Let the driver checksum.

Due to the skb length changes, TSO code is moved before the Tx descriptor gets
written.
