Atheros 6K WiFi USB adaptors

Atheros 6K WiFi USB adaptors

[Peter Tam]

I thought I saw support code usb.c for that AR6000 wifi chip set. I know there is extensive support for the SDIO interface version. But on detail examination, the usb.c code is missing a lot of hif_ops interfce routines.

The equivalents of 
.read_write_sync = ath6kl_sdio_read_write_sync,
.write_async = ath6kl_sdio_write_async,
.irq_enable = ath6kl_sdio_irq_enable,
.irq_disable = ath6kl_sdio_irq_disable,
.scatter_req_get = ath6kl_sdio_scatter_req_get,
.scatter_req_add = ath6kl_sdio_scatter_req_add,
.enable_scatter = ath6kl_sdio_enable_scatter,
.scat_req_rw = ath6kl_sdio_async_rw_scatter,
.cleanup_scatter = ath6kl_sdio_cleanup_scatter,

are missing in usb.c vs sdio.c for examples.

Can some decent soul tell me where
.read_write_sync = ath6kl_usb_read_write_sync,
.write_async = ath6kl_usb_write_async,
.irq_enable = ath6kl_usb_irq_enable,
.irq_disable = ath6kl_usb_irq_disable,
.scatter_req_get = ath6kl_usb_scatter_req_get,
.scatter_req_add = ath6kl_usb_scatter_req_add,
.enable_scatter = ath6kl_usb_enable_scatter,
.scat_req_rw = ath6kl_usb_async_rw_scatter,
.cleanup_scatter = ath6kl_usb_cleanup_scatter,

are sourced from?

The USB version should work equally well. Are you having problems with
USB version?

That's because of different HTC implementations. SDIO uses htc_mbox.c
and USB use htc_pipe.c and due to this there are differences in HIF
interface as well. I should document that better in the code.

Hi Peter,

please always CC linux-wireless and ath6kl-devel. I do not have the time
to give private support.

Like you mentioned in your other email you need to look at latest Linux
releases. The latest and greatest ath6kl is always available from
ath6kl.git:

Heh, I have never realised that. A funny conflict :)

I was talking about Host/Target Communication, which is a protocol used
in our firmware. You can have different channels (or endpoints) and
encapsulate various payload, both control and data packets.
