Instead distributions should simply ship the firmware in a package.

What can we do? Nothing.

Yes, well. You're not intermixing an earlier discussion into this, where you didn't indicate opensource capabilities to the kernel. If you indicate OS capabilities, you can use whatever offset you want, of course. > - what to do with rts procedure: we can implement this feature easily > but I'm not sure about the value it can add to people (the majority of > users?) that use the bcm board in station mode.

However, we put this task in the todo list. RTS/CTS is not specific to AP mode. It's used on any station in the BSS.

Yes, the old format is deprecated and will be removed soon. > - I would like to start considering N-phy on the firmware side.

Not sure, maybe there's more to do. I didn't try that, yet. Before you start, you'll have to verify whether the assembler works correctly. Same for the disassembler. -- Greetings, Michael. -- To unsubscribe from this list: send the line "unsubscribe linux-wireless" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
