Subject: Re: net: add PCINet driver


You can't set that NETIF_F_NO_CSUM if there is every an
intermediate node that forwards or inspects the packets.

And really, it should never be used for situations where
packets leave a single kernel's realm.  Really, I don't
trust the PCI bus to never ever corrupt DMA's to my disk
so NETIF_F_NO_CSUM is certainly not appropriate here.

Please post a new version of your patch, and also please
include any changes you've made since V3.

Thanks.
