Currently the flexcan driver uses hardware local echo. This blindly
echos all transmitted frames to all receiving sockets, regardless what
CAN_RAW_RECV_OWN_MSGS and CAN_RAW_LOOPBACK are set to.

This patch now submits transmitted frames to be echoed in the transmit
complete interrupt, preserving the reference to the sending
socket. This allows the can protocol to correctly handle the local
echo.

Further this patch moves tx_bytes statistic accounting into the tx_complete
handler.

The X520 family of network devices, with the 82599 chip, support a
small number of Intel-verified SFP+ modules on their NICs.  To maintain
stability and quality, the current devices restrict untested 3rd party
SFP+ modules.

This patch introduces a module parameter for ixgbe to allow these untested
modules at the user's peril.  It also includes a warning to the syslog
alerting users that the modules aren't supported, and results may
vary.

This function returns the page offset of the buffer, which can be
calculated based on either its DMA address or its virtual address.  It
used to use the virtual address and we would cast that to unsigned
long, as anything smaller would result in a compiler warning.  Now
that it's using the DMA address we should use unsigned int, matching
the return type.  It is also unnecessary to use __force.

The irq handler was a mess.

See 7ab87ff4 ("via-rhine: move work from
irq handler to softirq and beyond") for similar changes. One can notice:
- all non-napi tasks are explicitely scheduled trough a single work queue.
- hiding software tx queue start behind the rtl_hw_start method is mildly
  natural. Move it in the caller where needed.
- as can be seen from the heavy use of bh disabling locks, the driver is
  not safe for irq context messages with netconsole. It is still quite
  usable for general messaging though. Tested ok with concurrent registers
  dump (ethtool -d) + background traffic + "echo t > /proc/sysrq-trigger".

Tested with old PCI chipset, PCIe 8168 and 810x:
- XID 0c900800 RTL8168evl/8111evl
- XID 18000000 RTL8168b/8111b
- XID 98000000 RTL8169sc/8110sc
- XID 083000c0 RTL8168d/8111d
- XID 081000c0 RTL8168d/8111d
- XID 00b00000 RTL8105e
- XID 04a00000 RTL8102e

As a side note, the comments in f11a377b
("r8169: avoid losing MSI interrupts") does not seem completely clear: if
I hack the driver further to stop acking the irq link event bit, MSI
interrupts keep being delivered (RTL8168b/8111b, XID 18000000).

I see no good reason to keep both rtl8169_reinit_task and rtl8169_reset_task:
- rtl8169_reinit_task adds a software failure point which does relate to
  any hardware state
- they handle hardware the same. Remember that rtl8169_reinit_task was
  introduced in the 8169 only era to handle PCI errors way before the 8168
  asked for pll and firmware ops and compare :

      rtl8169_reinit_task     |    rtl8169_reset_task

The generic lib.c file contains code relative to the various MACs, NVM and
Manageability supported by the driver.  This patch splits the file into
three which are specific to those areas similar to how the PHY-specific
code is in phy.c and code specific to the 80003es2lan, 8257x, and ichX
MAC families are in their own files.  The generic code that is applicable
to all MAC/PHY parts supported by the driver remains in netdev.c, param.c
and ethtool.c files.  No change in functionality, just moving code
around for ease of maintenance, with some whitespace and other checkpatch
cleanups.
