This series contains fixes to e1000e only. Benjamin Poirier provides all but one fix in this series, starting with workaround for a VMWare e1000e emulation issue where ICR reads 0x0 on the emulated device. Partially reverted a previous commit dealing with the "Other" interrupt throttling to avoid unforeseen fallout from these changes that are not strictly necessary. Restored the ICS write for receive and transmit queue interrupts in the case that txq or rxq bits were set in ICR and the Other interrupt handler read and cleared ICR before the queue interrupt was raised. Fixed an bug where interrupts may be missed if ICR is read while INT_ASSERTED is not set, so avoid the problem by setting all bits related to events that can trigger the Other interrupt in IMS. Fixed the return value for check_for_link() when auto-negotiation is off.
Pierre-Yves Kerbrat fixes e1000e to use dma_zalloc_coherent() to make sure the ring is memset to 0 to prevent the area from containing garbage. v2: added an additional e1000e fix to the series The following are changes since commit a7f0fb1bfb66ded5d556d6723d691b77a7146b6f: Merge branch 'hv_netvsc-minor-fixes' and are available in the git repository at: git://git.kernel.org/pub/scm/linux/kernel/git/jkirsher/net-queue 1GbE Benjamin Poirier (5): e1000e: Remove Other from EIAC Partial revert "e1000e: Avoid receiver overrun interrupt bursts" e1000e: Fix queue interrupt re-raising in Other interrupt e1000e: Avoid missed interrupts following ICR read e1000e: Fix check_for_link return value with autoneg off Pierre-Yves Kerbrat (1): e1000e: allocate ring descriptors with dma_zalloc_coherent drivers/net/ethernet/intel/e1000e/defines.h | 21 ++++++++++++++++- drivers/net/ethernet/intel/e1000e/ich8lan.c | 2 +- drivers/net/ethernet/intel/e1000e/mac.c | 2 +- drivers/net/ethernet/intel/e1000e/netdev.c | 35 ++++++++++------------------- 4 files changed, 34 insertions(+), 26 deletions(-) -- 2.14.3
