1GbE Intel Wired LAN Driver Updates 2015-12-12

This series contains updates to e1000, e1000e and igb.

Joern Engel fixes up the e1000 driver to reduce scheduler latencies by
making the eeprom read/write functions scheduler friendly by using a mutex
lock instead of a spin lock.

Todd adds code for igb to initialize the 88E1543 PHY properly.  Then fixed
igb to use the correct i210 register for EEMNGCTL, since the i210 has two
EEPROM access registers (EEARBC and EEMNGCTL).

Dmitry Vyukov provides a fix for e1000 to resolve a data race found with
KernelThreadSanitizer (KTSAN), where no memory barriers were being used
when buffers get recycled, so the recycled buffers can be corrupted.  So
use smp_store_release() to update tx_ring->next_to_clean and
smp_load_acquire() to read tx_ring->next_to_clean to properly hand off
buffers from e1000_clean_tx_irq() to e1000_xmit_frame().

Jarod Wilson fixes igb so that we do not try to unmap a NULL hw_addr.  Then
cleaned up array_rd32() so that it uses igb_rd32() the same as rd32() and
use io_addr() in more places so that we do not have to call E1000_REMOVED().

Janusz Wolak cleans up the e1000 driver by correcting warnings produced
by checkpatch.pl for the driver.

Jean Sacren provides several patches with general cleanups for e1000 and
e1000e, which include code comment fix-ups and cleanup of local variables
not needed.

Dmitry Fleytman fixes a possible division by zero in the receive interrupt
handler for e1000e when working without adaptive interrupt moderation,
which is typically disabled on jumbo MTUs.

Raanan increases the timeout of the polling bit due to timing changes to
the ME firmware on a platform, so increase the timeout to 300ms.  Added
initial support for i219-LM, which is a LOM that will be available on
systems with the Lewisburg Platform Controller HUB (PCH) chipset.

Jan Beulich fixes a NULL dereference in igb, due to the adapter->vf _data
being NULL while adapter->vfs_allocated_count is non-zero.
