1GbE Intel Wired LAN Driver Updates 2017-01-06

This series contains updates/fixes to igb and e1000e.

Joe fixes indentation and improper line wrapping in igb.

David Singleton fixes an issue in e1000e where in systemd, where things
are done in parallel and can create a condition where e1000_shutdown is
called after e1000_close, hitting BUG_ON assert in free_msi_irqs.

Cao Jin fixes a code comment on the wakeup status register.  Also fixes
a possible NULL pointer dereference by using igb_adapter->io_addr
instead of e1000_hw->hw_addr in igb_configure_tx_ring().

Chris Arges works around a firmware issue, which can cause probe of i210
NIC to fail, so zero the page select register during igb_get_phy_id() to
workaround the issue.  Aaron Sierra adds also a check for this issue
during the initialization of PHY parameters to ensure that this same
issue happens after probe.

Todd fixes a possible race condition in close/suspend by extending
the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme().  Also adds i211 to a known i210/i211
workaround.

Hannu Lounento fixes inverted logic on a debug statement.

The issue comes when there are multiple threads attempting to use
the mailbox facility at the same time.
When DCB operations and interface up/down is run in a loop for every
0.1 sec, we observed mailbox collisions. And out of the two commands
one would fail with the present code, since we don't queue the second
command.

To overcome the above issue, added a queue to access the mailbox.
Whenever a mailbox command is issued add it to the queue. If its at
the head issue the mailbox command, else wait for the existing command
to complete. Usually command takes less than a milli-second to
complete.

Also timeout from the loop, if the command under execution takes
long time to run.

In reality, the number of mailbox access collisions is going to be
very rare since no one runs such abusive script.

Similar to ixgbe, when an interface is part of a namespace it is
possible that igb_close() may be called while __igb_shutdown() is
running which ends up in a double free WARN and/or a BUG in
free_msi_irqs().

Extend the rtnl_lock() to protect the call to netif_device_detach() and
igb_clear_interrupt_scheme() in __igb_shutdown() and check for
netif_device_present() to avoid calling igb_clear_interrupt_scheme() a

Whenever the igb driver detects the result of a read operation returns
a value composed only by F's (like 0xFFFFFFFF), it will detach the
net_device, clear the hw_addr pointer and warn to the user that adapter's
link is lost - those steps happen on igb_rd32().

In case a PCI error happens on Power architecture, there's a recovery
mechanism called EEH, that will reset the PCI slot and call driver's
handlers to reset the adapter and network functionality as well.

We observed that once hw_addr is NULL after the error is detected on
igb_rd32(), it's never assigned back, so in the process of resetting
the network functionality we got a NULL pointer dereference in both
igb_configure_tx_ring() and igb_configure_rx_ring(). In order to avoid
such bug, this patch re-assigns the hw_addr value in the slot_reset
handler.

Several people have reported firmware leaving the I210/I211 PHY's page
select register set to something other than the default of zero. This
causes the first accesses, PHY_IDx register reads, to access something
else, resulting in device probe failure:

    igb: Intel(R) Gigabit Ethernet Network Driver - version 5.4.0-k
    igb: Copyright (c) 2007-2014 Intel Corporation.
    igb: probe of 0000:01:00.0 failed with error -2

This problem began for them after a previous patch I submitted was
applied:

    commit 2a3cdead
    Author: Aaron Sierra <asierra@xes-inc.com>
    Date:   Tue Nov 3 12:37:09 2015 -0600

I personally experienced this problem after attempting to PXE boot from
I210 devices using this firmware:

    Intel(R) Boot Agent GE v1.5.78
    Copyright (C) 1997-2014, Intel Corporation

Resetting the PHY before reading from it, ensures the page select
register is in its default state and doesn't make assumptions about
the PHY's register set before the PHY has been probed.

During systemd reboot sequence network driver interface is shutdown
by e1000_close. The PCI driver interface is shut by e1000_shutdown.
The e1000_shutdown checks for netif_running status, if still up it
brings down driver. But it disables msi outside of this if statement,
regardless of netif status. All this is OK when e1000_close happens
after shutdown. However, by default, everything in systemd is done
in parallel. This creates a conditions where e1000_shutdown is called
after e1000_close, therefore hitting BUG_ON assert in free_msi_irqs.

tools: psock_tpacket: block Rx until socket filter has been added and socket has been bound to loopback.

Packets from any/all interfaces may be queued up on the PF_PACKET socket
before it is bound to the loopback interface by psock_tpacket, and
when these are passed up by the kernel, they could interfere
with the Rx tests.

Avoid interference from spurious packet by blocking Rx until the
socket filter has been set up, and the packet has been bound to the
desired (lo) interface. The effective sequence is
	socket(PF_PACKET, SOCK_RAW, 0);
	set up ring
	Invoke SO_ATTACH_FILTER
	bind to sll_protocol set to ETH_P_ALL, sll_ifindex for lo
After this sequence, the only packets that will be passed up are

For TCP sockets, TX timestamps are only captured when the user data
is successfully and fully written to the socket. In many cases,
however, TCP writes can be partial for which no timestamp is
collected.

Collect timestamps whenever any user data is (fully or partially)
copied into the socket. Pass tcp_write_queue_tail to tcp_tx_timestamp
instead of the local skb pointer since it can be set to NULL on
the error path.

Note that tcp_write_queue_tail can be NULL, even if bytes have been
copied to the socket. This is because acknowledgements are being
processed in tcp_sendmsg(), and by the time tcp_tx_timestamp is
called tcp_write_queue_tail can be NULL. For such cases, this patch
does not collect any timestamps (i.e., it is best-effort).

This patch is written with suggestions from Willem de Bruijn and
Eric Dumazet.

Change-log V1 -> V2:
	- Use sockc.tsflags instead of sk->sk_tsflags.
	- Use the same code path for normal writes and errors.

Fix the way enum values are translated into strings in AF_RXRPC
tracepoints.  The problem with just doing a lookup in a normal flat array
of strings or chars is that external tracing infrastructure can't find it.
Rather, TRACE_DEFINE_ENUM must be used.

Also sort the enums and string tables to make it easier to keep them in
order so that a future patch to __print_symbolic() can be optimised to try
a direct lookup into the table first before iterating over it.

A couple of _proto() macro calls are removed because they refered to tables
that got moved to the tracing infrastructure.  The relevant data can be
