All devices: - add support for rate adaptation via ieee80211_amrr(9); - use short preamble for transmitted frames when needed; - multi-bss support: * for RTL8821AU: 2 VAPs at the same time; * other: 1 any VAP + 1 sta VAP. RTL8188CE: - fix IQ calibration bug (reason of significant speed degradation); - add h/w crypto acceleration support. USB: - A-MPDU Tx support; - short GI support; Other: - add support for RTL8812AU / RTL8821AU chipsets (a/b/g/n only; no ac yet); - split merged code into subparts: * bus glue (usb/*, pci/*, rtl*/usb/*, rtl*/pci/*) * common (if_rtwn*) * chip-specific (rtl*/*) - various other bugfixes. Due to code reorganization, module names / requirements were changed too: urtwn urtwnfw -> rtwn rtwn_usb rtwnfw rtwn rtwnfw -> rtwn rtwn_pci rtwnfw Tested with RTL8188CE, RTL8188CUS, RTL8188EU and RTL8821AU. Tested by: kevlo, garga, Peter Garshtja <peter.garshtja@ambient-md.com>, Kevin McAleavey <kevin.mcaleavey@knosproject.com>, Ilias-Dimitrios Vrachnis <id@vrachnis.com>, <otacilio.neto@bsd.com.br> Relnotes: yes
