2006-06-23[NET]: Merge TSO/UFO fields in sk_buffHerbert Xu1-5/+5
Having separate fields in sk_buff for TSO/UFO (tso_size/ufo_size) is not going to scale if we add any more segmentation methods (e.g., DCCP). So let's merge them. They were used to tell the protocol of a packet. This function has been subsumed by the new gso_type field. This is essentially a set of netdev feature bits (shifted by 16 bits) that are required to process a specific skb. As such it's easy to tell whether a given device can process a GSO skb: you just have to and the gso_type field and the netdev's features field. I've made gso_type a conjunction. The idea is that you have a base type (e.g., SKB_GSO_TCPV4) that can be modified further to support new features. For example, if we add a hardware TSO type that supports ECN, they would declare NETIF_F_TSO | NETIF_F_TSO_ECN. All TSO packets with CWR set would have a gso_type of SKB_GSO_TCPV4 | SKB_GSO_TCPV4_ECN while all other TSO packets would be SKB_GSO_TCPV4. This means that only the CWR packets need to be emulated in software. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S. Miller <davem@davemloft.net>
2006-06-11[PATCH] e1000: prevent statistics from getting garbled during resetLinas Vepstas1-1/+7
If a PCI bus error/fault triggers a PCI bus reset, attempts to get the ethernet packet count statistics from the hardware will fail, returning garbage data upstream. This patch skips statistics data collection if the PCI device is not on the bus. This patch presumes that an earlier patch, [PATCH] PCI Error Recovery: e1000 network device driver has already been applied.

For some reason, E1000's ->hard_start_xmit() routine returns -EFAULT instead of one of the NETDEV_TX_* error codes. In fact, it frees up the SKB before returning this.
