First goal would be to exert BQL-like backpressure to the upper portions of the stack, then add in ampdu support (still with backpressure), etc. On 12/25/15 10:11 PM, Dirk Neukirchen wrote: > OpenWrt is often used to develop or test new devices > Some users might want to test and help to improve > this new driver > > upstream commit notice 26f1fad29ad973b0fb26a9ca3dcb2a73dde781aa > > New driver: rtl8xxxu (mac80211) > This is an alternate driver for a number of Realtek WiFi USB devices, > including RTL8723AU, RTL8188CU, RTL8188RU, RTL8191CU, and RTL8192CU. > It was written from scratch utilizing the Linux mac80211 stack. > > After spending months cleaning up the vendor provided rtl8723au > driver, which comes with it's own 802.11 stack included, I decided to > rewrite this driver from the bottom up. > > Many thanks to Johannes Berg for 802.11 insights and help and Larry > Finger for help with the vendor driver. > > The full git log for the development of this driver can be found here: > git git://git.kernel.org/pub/scm/linux/kernel/git/jes/linux.git > branch rtl8723au-mac80211 > > This driver is still under development, but has proven to be very > stable for me.
