This reverts commit 2a54eb5e1476426ee639bbfbe179b52342a0d82c. 94010fa0dd07e8b904e7c6b6589f15573008ab15 introduced MSI interrupts mode support, which seemed safe enough with RTL8188EE and RTL8723BE as RealTek's testing results, but some users reported their RTL8188EE modules could not connect to any wireless network after the MSI mode was enabled by Ubuntu 14.04. So, let's fallback to pin-based mode until rtlwifi's MSI support get good compatibility. BugLink: https://bugs.launchpad.net/bugs/1310512 Signed-off-by: Adam Lee <adam.lee@xxxxxxxxxxxxx>
ACK for both of these patches. I thought I had tested these patches when they first came through, but obviously I did not. I do not know which Realtek engineers you consulted, but they failed to supply you with the MSI handler. The Realsil group that actually does the coding for the PCI-based devices have supplied such a routine along with the driver for the RTL8192EE devices. With the handler, MSI does work. After I integrate that handler into rtlwifi, I will resubmit the patches turning on MSI for rtl8188ee and rtl8723ae.
