I can't find the wlan_ng request_firmware call in my wireless-testing tree (week or so old). Is that new? >From what I can tell the wlan_ng, hostap and orinoco drivers all program firmware that has the same basic format. Hostap doesn't use request_firmware, and gives userspace the control over the write sequence. orinoco places a very simple header in front of the binary image. Do we really want to add srec processing to the driver (or even the kernel)? It would be nice if the FW image was in the same format for orinoco and wlan_ng, as the prism firmware ought to work on non-USB prism cards, and we should be able to make orinoco use it.
