Hi!

interesting! ok. I wonder how hard it'd be to integrate this into the existing ral driver. All of the RAL "HAL" routines right now really are almost complete drivers themselves with some shared bus management glue. HOw hard does it look to integrate it?

Currently We have almost same code in these file.

sys/dev/ral/rt2860.c
sys/dev/usb/wlan/if_run.c

This code support PCI and USB. I can't check this code, because of I don't have PCI and USB module.

This is original README

FreeBSD 7.2 and 8.0 device drivers for Ralink rt2870 and rt2860 chips.

Features:

802.11abg
Security: WEP, TKIP, AES-CCMP
Modes: STA, Adhoc, HostAP, WDS
802.11n
- 20/40 MHz bandwidth channels
- Greenfield
- Short GI
- STBC
- A-MSDU Rx
- A-MPDU Tx/Rx
- Block Acknowledgements (BA)
- MIMO power save

I want add more support chip. But I don't know when that will be.

yamori813_yahoo.co.jp abandoned this revision.Sep 5 2018, 1:22 AM

I was going to try and commit this to -head soon, as it's a pretty stand-alone thing. even just before -head branches.

Do you want me to abandon it? or shall i try to get it into the tree as-is?

Thanks!

-a

I want add RT2880 and RT5350 and MT7620 support in this code. If I will done it, then I will put review again. Thanks.
