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.
