2006-06-23[NET]: Merge TSO/UFO fields in sk_buffHerbert Xu
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>
2006-06-23[NET]: Avoid allocating skb in skb_padHerbert Xu
First of all it is unnecessary to allocate a new skb in skb_pad since the existing one is not shared. More importantly, our hard_start_xmit interface does not allow a new skb to be allocated since that breaks requeueing. This patch uses pskb_expand_head to expand the existing skb and linearize it if needed. Actually, someone should sift through every instance of skb_pad on a non-linear skb as they do not fit the reasons why this was originally created. Incidentally, this fixes a minor bug when the skb is cloned (tcpdump, TCP, etc.). As it is skb_pad will simply write over a cloned skb. Because of the position of the write it is unlikely to cause problems but still it's best if we don't do it. Signed-off-by: Herbert Xu <herbert@gondor.apana.org.au> Signed-off-by: David S.

2006-06-22[PATCH] myri10ge - drop workaround pci_save_state() disabling MSI Brice Goglin
We don't need to restore the state right after saving it for later recovery since commit 99dc804d9bcc2c53f4c20c291bf4e185312a1a0c (PCI: disable msi mode in pci_disable_device) now prevents pci_save_state() from disabling MSI.

2006-06-22[PATCH] myri10ge - drop workaround for the missing AER ext cap on nVidia CK804 Brice Goglin
We don't need to hardcode the AER capability of the nVidia CK804 chipset anymore since commit cf34a8e07f02c76f3f1232eecb681301a3d7b10b (PCI: nVidia quirk to make AER PCI-E extended capability visible) now makes sure that this cap will be available to pci_find_ext_capability().

2006-06-08[PATCH] myri10ge updateBrice Goglin
The following patch updates the myri10ge to 1.0.0, with the following changes: * Switch to dma_alloc_coherent API. * Avoid PCI burst when writing the firmware on chipset with unaligned completions. * Use ethtool_op_set_tx_hw_csum instead of ethtool_op_set_tx_csum. * Include linux/dma-mapping.h to bring DMA_32/64BIT_MASK on all architectures (was missing at least on alpha). * Some typo and warning fixes.
