sky2: Fix checksum endianness

2009-08-16T21:18:10Z

[ Upstream commit b9389796fa4c87fbdff33816e317cdae5f36dd0b ] sky2 driver on PowerPC targets floods kernel log with following errors: eth1: hw csum failure. Call Trace: [ef84b8a0] [c00075e4] show_stack+0x50/0x160 (unreliable) [ef84b8d0] [c02fa178] netdev_rx_csum_fault+0x3c/0x5c [ef84b8f0] [c02f6920] __skb_checksum_complete_head+0x7c/0x84 [ef84b900] [c02f693c] __skb_checksum_complete+0x14/0x24 [ef84b910] [c0337e08] tcp_v4_rcv+0x4c8/0x6f8 [ef84b940] [c031a9c8] ip_local_deliver+0x98/0x210 [ef84b960] [c031a788] ip_rcv+0x38c/0x534 [ef84b990] [c0300338] netif_receive_skb+0x260/0x36c [ef84b9c0] [c025de00] sky2_poll+0x5dc/0xcf8 [ef84ba20] [c02fb7fc] net_rx_action+0xc0/0x144 The NIC is Yukon-2 EC chip revision 1. Converting checksum field from le16 to CPU byte order fixes the issue. Signed-off-by: Anton Vorontsov Signed-off-by: David S. Miller Signed-off-by: Greg Kroah-Hartman

sky2: don't look for VPD size

2009-07-02T23:49:42Z

[ Upstream commit 6cc90a5a6061428358d0f726a53fb44af5254111 ] The code to compute VPD size didn't handle some systems that use chip without VPD. Also some of the newer chips use some additional registers to store the actual size, and wasn't worth putting the additional complexity in, so just remove the code. No big loss since the code to set the VPD size was only a convenience so that utilities would not read the extra space past the end of the available VPD. Move the first PCI config read earlier to detect bad hardware where it returns all ones and refuse loading driver before furthur damage.

sky2: set VPD size

2009-02-03T23:08:36Z

Read configuration register during probe and use it to size the available VPD. Move existing code using same register slightly earlier in probe handling. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

sky2: move VPD display into debug interface

2009-02-03T23:08:36Z

The VPD stuff has more data and isn't generally that useful, so move it into the existing debugfs display and use the new PCI VPD accessor routines. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

sky2: handle dma mapping errors

2009-02-03T23:08:35Z

On non-x86 platforms it is possible to run out of DMA mapping resources. The driver was ignoring this and could cause corruptions. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

sky2: remove unneede workaround

2009-02-03T23:08:34Z

This workaround is not needed. It was inherited from sk98lin driver but only applies to an early development version of the chip that is not supported by sky2. The workaround required an unnecessary pci read which hurts performance Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller

sky2: fix hard hang with netconsoling and iface going up

Printing anything over netconsole before hw is up and running is, of course, not going to work. Signed-off-by: Alexey Dobriyan Acked-by: Stephen Hemminger Signed-off-by: David S. Miller

netdev: add more functions to netdevice ops

2008-11-21T04:14:53Z

This patch moves neigh_setup and hard_start_xmit into the network device ops structure. For bisection, fix all the previously converted drivers as well. Bonding driver took the biggest hit on this. Added a prefetch of the hard_start_xmit in the fast path to try and reduce any impact this would have. Signed-off-by: Stephen Hemminger Signed-off-by: David S. Miller
