Content-Type: text/plain; format=flowed; charset="iso-8859-1" Cc: tnt@246tNt.com List-Id: Linux on Embedded PowerPC Developers Mail List List-Unsubscribe: , List-Archive: List-Post: List-Help: List-Subscribe: , Hi We are showing figures of more than 4 billion error frames in our=20 ethernet interfaces. We have tested that the problem is in a=20 substraction (the number of errors decrements with the number of = frames). So... looking in the fec driver (fec.c) for the calculations we have=20 seen that the number of multicast packets is added to the number of=20 correct frames in order to get the frame errors... But the interesting thing is that we have checked that this calculation=20 is something that we have added with a patch by Grzegorz Bernacki in=20 this list. So... The funny thing is... Why a patch that solves the problem for=20 Grzegorz produces "the same problem" for us? And... by the way... I have seen IEEE802.3, and when they talk about=20 aFramesReceivedOK (which I suppose is the ieee_r_frame_ok in the=20 driver), and they do not say a word about not including multicast=20 packets in it... Any comment will be appreciate.
