Hi, all, I have read the http://www.spinics.net/lists/linux-wireless/msg124980.html for patching the ath9k driver in compat-wireless-2014-05-22 in openwrt trunk, but when I patch, for example, “the [PATCH 01/10] ath9k: export methods related to ack timeout estimation”, it failed. the command window showed that: patching file drivers/net/wireless/ath/ath9k/hw.h Hunk #1 FAILED at 1080. 1 out of 1 hunk FAILED -- saving rejects to file drivers/net/wireless/ath/ath9k/hw.h.rej. i have checked the hw.h file, but I can not see anything wrong, how should i do further? another question is,if I patch them manualy,I can not see the dnyack choice in the menuconfig,what should I do then? I am waiting for your suggestions. from jammy's iPhone-- 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
