Remove any chipset specific usage of Rx descriptor structure / bits
from common code to prevent misuse of fields that may differ
between various chipsets.
Checked with: RTL8821AU in STA mode.
- Increase Rx buffer size from MCLBYTES to MJUMPAGESIZE.
- Provide an additional defragmentation routine for frames larger
than MCLBYTES; that is required by A-MSDU / Atheros Fast-Frames
support to work with current Tx path implementation.
Enabled features list for RTL8188CE:
- Atheros Fast-Frames;
- A-MPDU (Tx / Rx);
- A-MSDU (Tx / Rx; 4k only);
- Short Guard Interval.
Tested with:
- RTL8188CE (STA+AP) + RTL8821AU (STA).
- RTL8188CE (STA) + RTL8188CUS (AP).
Relnotes: yes
rtwn_usb: drain USB transfers during device shutdown; this fixes possible
panic with 'options IEEE80211_SUPPORT_SUPERG' during device detach.
Tested with RTL8188CE, STA mode.
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.
