Subject: [PATCH] Clean up 'FLAG_POINTTOPOINT' and 'FLAG_MULTI_PACKET' overlaps in usbnet.h
Date: Thu, 14 Apr 2011 09:43:32 +0800 [thread overview]
Message-ID: <BANLkTinyWLjVRLKTZB09BZaH2o0gB0p8JA@mail.gmail.com> (raw)
USB tethering does not work anymore since 2.6.39-rc2, but it's okay in
-rc1. The root cause is the new added mask code 'FLAG_POINTTOPOINT'
overlaps 'FLAG_MULTI_PACKET' in include/linux/usb/usbnet.h, this
causes logic issue in rx_process(). This patch cleans up the overlap.
