2007-04-25[SK_BUFF]: Introduce skb_reset_mac_header(skb)Arnaldo Carvalho de Melo
For the common, open coded 'skb->mac.raw = skb->data' operation, so that we can later turn skb->mac.raw into a offset, reducing the size of struct sk_buff in 64bit land while possibly keeping it as a pointer on 32bit. This one touches just the most simple case, next will handle the slightly more "complex" cases. Signed-off-by: Arnaldo Carvalho de Melo <acme@redhat.com> Signed-off-by: David S.

The packet driver is assuming (reasonably) that the (undocumented) request.errors is an errno. But it is in fact some mysterious bitfield.

2007-04-24usb-net/pegasus: fix pegasus carrier detectionDan Williams
Broken by 4a1728a28a193aa388900714bbb1f375e08a6d8e which switched the return semantics of read_mii_word() but didn't fix usage of read_mii_word() to conform to the new semantics. Setting carrier to off based on the NO_CARRIER flag is also incorrect as that flag only triggers on TX failure and therefore isn't correct when no frames are being transmitted. Since there is already a 2*HZ MII carrier check going on, defer to that. Add a TRUST_LINK_STATUS feature flag for adapters where the LINK_STATUS flag is actually correct, and use that rather than the NO_CARRIER flag.

2007-04-24sis900: Allocate rx replacement buffer before rx operationNeil Horman
The sis900 driver appears to have a bug in which the receive routine passes the skbuff holding the received frame to the network stack before refilling the buffer in the rx ring. If a new skbuff cannot be allocated, the driver simply leaves a hole in the rx ring, which causes the driver to stop receiving frames and become non-recoverable without an rmmod/insmod according to reporters. This patch reverses that order, attempting to allocate a replacement buffer first, and receiving the new frame only if one can be allocated. If no skbuff can be allocated, the current skbuf in the rx ring is recycled, dropping the current frame, but keeping the NIC operational.

2007-04-24[netdrvr] depca: handle platform_device_add() failureAndrea Righi
The following patch fixes a kernel bug in depca_platform_probe(). We don't use a dynamic pointer for pldev->dev.platform_data, so it seems that the correct way to proceed if platform_device_add(pldev) fails is to explicitly set the pldev->dev.platform_data pointer to NULL, before calling the platform_device_put(pldev), or it will be kfree'ed by platform_device_release().

This reverts commit 60cba200f11b6f90f35634c5cd608773ae3721b7. It's been linked to lockups of the e1000 hardware, see for example https://bugzilla.redhat.com/bugzilla/show_bug.cgi?id=229603 but it's likely that the commit itself is not really introducing the bug, but just allowing an unrelated problem to rear its ugly head (ie one current working theory is that the code exposes us to a hardware race condition by decreasing the amount of time we spend in each NAPI poll cycle). We'll revert it until root cause is known. Intel has a repeatable reproduction on two different machines and bus traces of the hardware doing something bad.

It is also possible to do Jumbo mode, but it means turning off TSO and checksum offload so the performance gets worse. There isn't enough buffering for checksum offload to work.
