The rtl8187 cards don't seem to receive multicast frames, which, among other things, makes them fail to receive RAs in IPv6 networks. The cause seems to be that the RTL818X_RX_CONF_MULTICAST flag doesn't have the desired effect. Fix the issue by setting RTL818X_RX_CONF_MONITOR instead, which puts the card into monitor mode and resolves the problem so that multicast frames are sucessfully passed to the kernel. The existence of the problem and the effectiveness of the solution has originally been confirmed on an 8187B based card with the USB id of 0bda:8197. Subsequent testing by Larry Finger on an 8187L based card, which follows the second (8187, i.e. "non-b") code path in the driver, has confirmed that the fix does not cause any noticeable regresssions there either.

Linux kernel ============ This file was moved to Documentation/admin-guide/README.rst Please notice that there are several guides for kernel developers and users. These guides can be rendered in a number of formats, like HTML and PDF. In order to build the documentation, use ``make htmldocs`` or ``make pdfdocs``. There are various text files in the Documentation/ subdirectory, several of them using the Restructured Text markup notation. See Documentation/00-INDEX for a list of what is contained in each file. Please read the Documentation/process/changes.rst file, as it contains the requirements for building and running the kernel, and information about the problems which may result by upgrading your kernel.
