In OpenWrt, we use backports to stay up to date with current wireless drivers without being forced into frequently updating the kernels as well. We support many different platforms, and sometimes it takes a while to update the kernel on them. Using backports significantly reduces the amount of effort that we need to put into maintaining the wireless drivers. When making changes to wireless drivers or mac80211, which I submit upstream, I also develop them in our most recent backports snapshot first (typically generated from wireless-testing). When they are done, I port them to a proper git tree and submit them from there. In OpenWrt, we typically update the backports snapshot outside of the normal kernel release cycle (always to latest wireless-testing) and stabilize that by cherry-picking individual patches on top of it. - Felix -- To unsubscribe from this list: send the line "unsubscribe linux-kernel" in the body of a message to majordomo@vger.kernel.org More majordomo info at http://vger.kernel.org/majordomo-info.html Please read the FAQ at http://www.tux.org/lkml/
