When we are talking about small form factor. Did you know that OpenWRT has enabled ath9k's debugfs feature by default? Even the image for my TL-WR841ND [just a 4MiB flash] has it enabled! So I don't that's much of a problem. Even more the debugfs bits are probably smaller than all those initvals [you know, those for the whole AR5008/AR91XX/AR92XX/AR93XX/AR94XX gang] they have to carry around. [Yeah, if you use the same rev-chips on your stuff, you could get away with just one initval... Think of the savings!] Regards, Chr -- 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
