E100: fix interaction with swiotlb on X86.

2009-09-15T17:45:10Z

[ Upstream commit 6ff9c2e7fa8ca63a575792534b63c5092099c286 ] E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Data in descriptors is accessed simultaneously by the chip (writing status and size when a packet is received) and CPU (reading to check if the packet was received). This isn't a valid usage of PCI DMA API, which requires use of the coherent (consistent) memory for such purpose. Unfortunately e100 chips working in "simplified" RX mode have to store received data directly after the descriptor. Fixing the driver to conform to the API would require using unsupported "flexible" RX mode or receiving data into a coherent memory and using CPU to copy it to network buffers. This patch, while not yet making the driver conform to the PCI DMA API, allows it to work correctly on X86 with swiotlb (while not breaking other architectures).

E100: work around the driver using streaming DMA mapping for RX descriptors.

2009-08-16T21:18:08Z

[ Upstream commit 303d67c288319768b19ed8dbed429fef7eb7c275 ] E100 places it's RX packet descriptors inside skb->data and uses them with bidirectional streaming DMA mapping. Unfortunately it fails to transfer skb->data ownership to the device after it reads the descriptor's status, breaking on non-coherent (e.g., ARM) platforms. This have to be converted to use coherent memory for the descriptors. Signed-off-by: Krzysztof Halasa Acked-by: Jeff Kirsher Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

e100: do not go D3 in shutdown unless system is powering off

2009-04-29T05:42:39Z

After experimenting with kexec with the last merges after 2.6.29, I've had some problems when probing e100. It would not read the eeprom. After some bisects, I realized this has been like that since forever (at least 2.6.18). The problem is that shutdown is doing the same thing that suspend does and puts the device in D3 state. I couldn't find a way to get the device back to a sane state in the probe function. So, based on some similar patches from Rafael J. Wysocki for e1000, e1000e, and ixgbe, I wrote this one for e100.

e100: add support for 82552 10/100 adapter

2009-03-21T20:25:25Z

This patch enables support for the new Intel 82552 adapter (new PHY paired with the existing MAC in the ICH7 chipset). No new features are added to the driver, however there are minor changes due to updated registers and a few workarounds for hardware errata.

net: Remove redundant NAPI functions

2009-01-21T22:33:50Z

Following the removal of the unused struct net_device * parameter from the NAPI functions named *netif_rx_* in commit 908a7a1, they are exactly equivalent to the corresponding *napi_* functions and are therefore redundant.

net: Remove unused netdev arg from some NAPI interfaces.

2008-12-23T04:43:12Z

When the napi api was changed to separate its 1:1 binding to the net_device struct, the netif_rx_[prep|schedule|complete] api failed to remove the now vestigual net_device structure parameter. This patch cleans up that api by properly removing it.. Signed-off-by: Neil Horman Signed-off-by: David S. Miller

e100: cleanup link up/down messages

2008-11-27T08:23:37Z

The system log messages created on a link status change need to follow a specific format to work with tools some customers use. This also makes the messages consistant with other Intel driver link messages. Signed-off-by: Jeff Kirsher Signed-off-by: David S. Miller
