Merge branch 'master' of git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/next-queue
Jeff Kirsher says: ==================== Intel Wired LAN Driver Updates 2015-06-03 This series contains updates to e1000e only. Yanir provides 8 fixes and 1 version bump for e1000e. First fix resolves a possible unit hang if multiple descriptors are available in the rings during reset or runtime suspend. Fixed a warning on SPARC compile based on a suggested solution from Alex Duyck. Fixed a logical error, where a "if" condition under which a flush should occur, was revered. Fixed a hardware issue that prevented i219 from working in legacy interrupts mode. Fixed the hardware clock configuration and suprious non-linear increment. Lastly, fixed a system hang which occurred during execution of "ethtool -t <NIC>", by disabling MULR for the loopback test to avoid the hand state. ==================== Signed-off-by: David S. Miller <davem@davemloft.net>
