With the Intel 82527EI (driver: e1000e) there is an issue when running
the ptpd2 program, that leads to a kernel oops. The reason is here that
in e1000_xmit_frame() a work queue will be scheduled that has not been
initialized in this case. The work queue "tx_hwstamp_work" will only be
initialized if adapter->flags & FLAG_HAS_HW_TIMESTAMP set. This check
is missing in e1000_xmit_frame().
The following patch adds the missing check.

Pull networking updates from David Miller:
1) New offloading infrastructure and example 'rocker' driver for
offloading of switching and routing to hardware.
This work was done by a large group of dedicated individuals, not
limited to: Scott Feldman, Jiri Pirko, Thomas Graf, John Fastabend,
Jamal Hadi Salim, Andy Gospodarek, Florian Fainelli, Roopa Prabhu
2) Start making the networking operate on IOV iterators instead of
modifying iov objects in-situ during transfers. Thanks to Al Viro
and Herbert Xu.
3) A set of new netlink interfaces for the TIPC stack, from Richard
Alpe.
4) Remove unnecessary looping during ipv6 routing lookups, from Martin
KaFai Lau.
5) Add PAUSE frame generation support to gianfar driver, from Matei
Pavaluca.
6) Allow for larger reordering levels in TCP, which are easily
achievable in the real world right now, from Eric Dumazet.
7) Add a variable of napi_schedule that doesn't need to disable cpu
interrupts, from Eric Dumazet.
8) Use a doubly linked list to optimize neigh_parms_release(), from
Nicolas Dichtel.
9) Various enhancements to the kernel BPF verifier, and allow eBPF
programs to actually be attached to sockets. From Alexei
Starovoitov.
10) Support TSO/LSO in sunvnet driver, from David L Stevens.
11) Allow controlling ECN usage via routing metrics, from Florian
Westphal.
12) Remote checksum offload, from Tom Herbert.

15) Support wildcard tunnel endpoints in ipv6 tunnels, from Steffen
Klassert.
16) Do gro flushes on a per-device basis using a timer, from Eric
Dumazet. This tries to resolve the conflicting goals between the
desired handling of bulk vs. RPC-like traffic.

received/steered, via SO_INCOMING_CPU. From Eric Dumazet.
18) Limit GSO packets to half the current congestion window, from Eric

This change replaces calls to netdev_alloc_skb_ip_align with
napi_alloc_skb. The advantage of napi_alloc_skb is currently the fact that
the page allocation doesn't make use of any irq disable calls.
There are few spots where I couldn't replace the calls as the buffer
allocation routine is called as a part of init which is outside of the
softirq context.

Update the Intel Ethernet drivers to use eth_skb_pad() and skb_put_padto
instead of doing their own implementations of the function.
Also this cleans up two other spots where skb_pad was called but the length
and tail pointers were being manipulated directly instead of just having
the padding length added via __skb_put.

This device claims TSO support for vlans. It also allows a
user to control vlan acceleration offloading. As such, it is
possible to turn off vlan acceleration and configure a vlan
which will continue to support TSO.
In such situation the packet passed down the the device will contain
a vlan header and skb->protocol will be set to ETH_P_8021Q.
The device assumes that skb->protocol contains network protocol
value and uses that value to set up TSO information. This results
in corrupted frames sent on the wire. Corruptions include
incorrect IP total length and invalid IP checksum.
This patch extract the protocol value correctly and corrects TSO
for non-accelerated traffic.

The process of shutting down the system causes a call to the close PM
callback. The reset in close causes a loss of link, and the resultant
LSC interrupt causes the Runtime PM idle callback to be called. The
check for link (while link is down) in the idle callback is wiping the
information about the EEE ability of the link partner. The information is
still gone when the PHY is powered back up in the shutdown flow. This
causes EEE in S5 to fail when Runtime PM is active.
Save the link partner's EEE ability in the idle callback so that a Runtime
PM event will not cause a loss of this information.

On I217 and newer hardware, EEE is enabled in the PHY by the software
when link is up and disabled by the hardware when link is lost.
To enable EEE in Sx (When both ends of the link support, and are enabled
for, EEE and 100Mbps), we need to disable LPLU and configure the PHY to
automatically enable EEE when link is up, since there will be no software
to complete the task.
To configure this in the PHY, the Auto Enable LPI bit in the Low Power
Idle GPIO Control register must be set. For normal operation in S0, this
bit must be cleared.

Previously, the check to turn on promiscuous mode only took into account
the total number of SHared Receive Address (SHRA) registers and if the
request was for a register within that range. It is possible that the
Management Engine might have locked a number of SHRA and not allowed a
new address to be written to the requested register.
Add a function to determine the number of unlocked SHRA registers. Then
determine if the number of registers available is sufficient for our needs,
if not then return -ENOMEM so that UNICAST PROMISC mode is activated.
Since the method by which ME claims SHRA registers is non-deterministic,
also add a return value to the function attempting to write an address
to a SHRA, and return a -E1000_ERR_CONFIG if the write fails. The error
will be passed up the function chain and allow the driver to also set
UNICAST PROMISC when this happens.

The netlink conflict dealt with moving to netlink_capable() and

in non-init namespaces. These were simple transformations from
netlink_capable to netlink_ns_capable.

Several customers have reported a link flap issue on 82579. The symptoms
are random and intermittent link losses when 82579 is connected to specific
link partners. Issue has been root caused as interoperability problem
between 82579 and at least some Broadcom PHYs in the Energy Efficient
Ethernet wake mechanism.
To fix the issue, we are disabling the Phase Locked Loop shutdown in 100M
Low Power Idle. This solution will cause an increase of power in 100M EEE
link. It will cost additional 28mW in this specific mode.

This is a workaround for a HW erratum on 82579 devices.
Erratum is #23 in Intel 6 Series Chipset and Intel C200 Series Chipset
specification Update June 2013.
Problem: 82579 parts experience packet loss in Gig and 100 speeds
when interconnect between PHY and MAC is exiting K1 power saving state.
This was previously believed to only affect 1Gig speed, but has been observed
at 100Mbs also.
Workaround: Disable K1 for 82579 devices at Gig and 100 speeds.

When changing the interface mtu, the driver starts with a value
that doesn't include VLAN_HLEN. Later tests in the driver
set the rx_buffer_len based on the mtu. As a result, when
the user increases the mtu to 1504 (to support 802.1AD for example),
the driver rx_buffer_len does not change and frames longer
the 1522 bytes are rejected as too long.
Include VLAN_HLEN from the start so that an user mtu greater then
1500 bytes is correctly reflected in the driver rx_buffer_len.

In commit da1e2046e5, the flow for enabling/disabling an Si errata
workaround (e1000_lv_jumbo_workaround_ich8lan) was changed to fix a problem
with iAMT connections dropping on interface down with jumbo frames set.
Part of this change was to move the function call disabling the workaround
to e1000e_down() from the e1000_setup_rctl() function. The mechanic for
disabling of this workaround involves writing several MAC and PHY registers
back to hardware defaults.
After this commit, when the driver is loaded with the cable out, the PHY
registers are not programmed with the correct default values. This causes
the device to be capable of transmitting packets, but is unable to recieve
them until this workaround is called.
The flow of e1000e's open code relies upon calling the above workaround to
expicitly program these registers either with jumbo frame appropriate settings
or h/w defaults on 82579 and newer hardware.
Fix this issue by adding logic to e1000_setup_rctl() that not only calls
e1000_lv_jumbo_workaround_ich8lan() when jumbo frames are set, to enable the
workaround, but also calls this function to explicitly disable the workaround
in the case that jumbo frames are not set.

error when PM is disabled:
