This package contains a kernel module for Realtek RTL8187SE mini PCI WLAN-Cards (PCI-ID 10ec:8199), which can be found in MSI Wind laptops.
The driver will be called "r8187se.ko"
This driver has been deleted from staging in 3.15, mac80211-based driver rtl818x_pci will support the device ID 10EC:8199 of deprecated r8187se driver in >= linux 3.15.
Although having a "proper" mac80211-based driver is the better long term solution, there are still some problems with this approach (weak signal, connection drops, etc.), so until support for these cards through rtl818x_pci has matured, you can use this driver as a fallback option.
Patches are taken from:
This package also contains a udev rule prefering the r8187se driver only for PCI-ID 10EC:8199 so no blacklisting of rtl818x_pci is needed.
