2006-09-12[PATCH] e1000: fix TX timout hang regression for 82542rev3Auke Kok
Commit 581d708eb47cccb5f41bc0817e50c9b004011ba8 (oct. 5 2005) introduced partial Multiqueue support for e1000 which broke macro smartness in setting up head/tail registers for 82542 rev3 chipsets, making these adapters completely non-working since 2.6.15. This commit sets the proper head and tail registers for read and write descriptor rings. Ths fix was tested on an 82542 rev3 NIC and newer NICs.

2006-06-27e1000: rework driver hardware reset lockingAuke Kok

This fixes all occurences where the driver needs to reset the mac. We also remove irq requesting/releasing into _open and _close so that while the device is _up we will never touch the irq's. This fixes the double free irq bug that people saw. To make sure that the watchdog task doesn't cause another race we let it run as a non-scheduled task.

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>
2006-06-11[PATCH] e1000: prevent statistics from getting garbled during resetLinas Vepstas
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.
