====================
tcp: change pingpong to 3 in delayed ack logic
TCP receiver today tries not to delay the ACKs to speed up the initial
slow start (a.k.a QUICK ACK mechanism). However the previous design
does not work well with modern TCP applications that starts with an
application-level handshake. For example, a HTTPs server often
receives the SSL hello and responds right away which triggers the TCP
stack to stop the quick ack and start delaying the ACKs based only one
instance of ping-pong. This patchset changes the threshold from 1 to 3
ping-pong transactions, so that we only start to delay the acks after
the receiver responds data quickly three times.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
In order to be more confident about an on-going interactive session, we
increment pingpong count by 1 for every interactive transaction and we
adjust TCP_PINGPONG_THRESH to 3.
This means, we only consider a session in pingpong mode after we see 3
interactive transactions, and start to activate delayed acks in quick
ack mode.
And in order to not over-count the credits, we only increase pingpong
count for the first packet sent in response for the previous received
packet.
This is mainly to prevent delaying the ack immediately after some
handshake protocol but no real interactive traffic pattern afterwards.

Instead of using pingpong as a single bit information, we refactor the
code to treat it as a counter. When interactive session is detected,
we set pingpong count to TCP_PINGPONG_THRESH. And when pingpong count
is >= TCP_PINGPONG_THRESH, we consider the session in pingpong mode.
This patch is a pure refactor and sets foundation for the next patch.
This patch itself does not change any pingpong logic.

The LAN743x includes on chip One-Time-Programmable (OTP) memory.
This patch extends the ethtool EEPROM read/write interface to
access OTP memory space.
The currently existing interface is limited, as it does not
allow OTP read, and OTP writes are restricted to
offset==0, length==512, and data[0]==0xF3.
This patch removes these restrictions and adds a private flag
called OTP_ACCESS, which is used to switch between EEPROM, and
OTP modes.
The private flag OTP_ACCESS is configurable through the
ethtool --set-priv-flags command.
And visible through the
ethtool --show-priv-flags command.
By default OTP_ACCESS is false, and there for previously existing
EEPROM commands will work exactly the same. However now access to
OTP requires one extra step of setting OTP_ACCESS to true. This
flag controls the read, write, and length reporting, functions
of ethtool.
EEPROM presence is not checked when setting or clearing this flag.
If the EEPROM is not present, the user, as before, will need to
diagnose that using existing read and write function of ethtool,
while OTP_ACCESS is false.
Updates for V2:
Added comments as to why this patch is needed.
Added comments explaining that EEPROM presence is not check
when setting or clearing the OTP_ACCESS flag.
Added length checking to all otp/eeprom read/write functions.

For revision 0x20, vlan filter is always bypassed when enable
broadcast promisc mode. In this case, broadcast packets with
any vlan id can be accpeted. We should disable broadcast promisc
mode until user want enable it.

Currently hclge_ieee_setets returns error directly when there is
error, which may cause netdev not up problem.
This patch adds some error handling when setting ETS configuration

r8169: add EEE support for RTL8168f
This series adds EEE support for RTL8168f. Again first patch adds the
support, and second patch enables EEE per default.
====================
Signed-off-by: David S. Miller <davem@davemloft.net>
Add EEE support for RTL8168f to the recently added EEE handling
framework in the driver. This patch leaves the chip defaults, means
EEE typically is disabled initially and it's up to the user to enable
it via ethtool.

Accept MSG_ZEROCOPY in all the TCP states that allow sendmsg. Remove
the explicit check for ESTABLISHED and CLOSE_WAIT states.
This requires correctly handling zerocopy state (uarg, sk_zckey) in
all paths reachable from other TCP states. Such as the EPIPE case
in sk_stream_wait_connect, which a sendmsg() in incorrect state will
now hit. Most paths are already safe.
Only extension needed is for TCP Fastopen active open. This can build
an skb with data in tcp_send_syn_data. Pass the uarg along with other
fastopen state, so that this skb also generates a zerocopy
notification on release.
Tested with active and passive tcp fastopen packetdrill scripts at

Use DEFINE_DEBUGFS_ATTRIBUTE rather than DEFINE_SIMPLE_ATTRIBUTE
for debugfs files.
Semantic patch information:
Rationale: DEFINE_SIMPLE_ATTRIBUTE + debugfs_create_file()
imposes some significant overhead as compared to
DEFINE_DEBUGFS_ATTRIBUTE + debugfs_create_file_unsafe().

====================
r8169: add EEE support for RTL8168g+
This series adds general EEE support to be used with ethtool.
In addition it implements EEE for chip versions from RTL8168g.
The first patch leaves the default chip settings and the
second enables EEE per default. This allows us to revert patch 2
w/o removing EEE support completely if we should face issues with
EEE on particular chip versions.
Unfortunately Realtek decided not to use the standard EEE MMD
registers but to use proprietary registers. Therefore we can't
use phylib functions like phy_ethtool_set_eee and have to
reimplement the functionality.
Tested on a system with RTL8168g (chip version 40).

This patch adds the general framework to deal with EEE in this driver
plus EEE support for chip versions from RTL8168g. We don't touch the
default chip settings, therefore EEE will usually be disabled and it's
up to the user to enable it.
