mt76: dma: fix buffer unmap with non-linear skbs

2019-10-30T14:59:48+00:00

mt76 dma layer is supposed to unmap skb data buffers while keep txwi
mapped on hw dma ring. At the moment mt76 wrongly unmap txwi or does
not unmap data fragments in even positions for non-linear skbs. This
issue may result in hw hangs with A-MSDU if the system relies on IOMMU
or SWIOTLB. Fix this behaviour properly unmapping data fragments on
non-linear skbs.

mt76: mt76x2e: disable pcie_aspm by default

2019-10-30T14:59:46+00:00

On same device (e.g. U7612E-H1) PCIE_ASPM causes continuous mcu hangs and
instability. Since mt76x2 series does not manage PCIE PS states, first we
try to disable ASPM using pci_disable_link_state. If it fails, we will
disable PCIE PS configuring PCI registers.
This patch has been successfully tested on U7612E-H1 mini-pice card

mt76: mt7615: fix mt7615 firmware path definitions

2019-09-24T14:45:30+00:00

mt7615 patch/n9/cr4 firmwares are available in mediatek folder in
linux-firmware repository. Because of this mt7615 won't work on regular
distributions like Ubuntu. Fix path definitions.  Moreover remove useless
firmware name pointers and use definitions directly
