2009-06-08net: skb_shared_info optimizationEric Dumazet
skb_dma_unmap() is quite expensive for small packets, because we use two different cache lines from skb_shared_info. One to access nr_frags, one to access dma_maps[0] Instead of dma_maps being an array of MAX_SKB_FRAGS + 1 elements, let dma_head alone in a new dma_head field, close to nr_frags, to reduce cache lines misses. Tested on my dev machine (bnx2 & tg3 adapters), nice speedup ! Signed-off-by: Eric Dumazet <eric.dumazet@gmail.com> Signed-off-by: David S. Miller <davem@davemloft.net>

2009-06-07ixgbe: Add FW detection and warning for 82599 SFP+ adaptersPeter P Waskiewicz Jr
82599 has a FW running that helps manage the internal SFI PHY. There are also a number of pre-production samples of these SFI-based devices in the field. This patch adds a check to look for the firmware running on all SFP+ based adapters, and displays a warning to the system log if a pre-production adapter is identified. The driver will continue loading though, with no functional degradation. Also remove an old function prototype from ixgbe_82599.c that isn't being used.

2009-05-29net: convert unicast addr listJiri Pirko
This patch converts unicast address list to standard list_head using previously introduced struct netdev_hw_addr. It also relaxes the locking. Original spinlock (still used for multicast addresses) is not needed and is no longer used for a protection of this list. All reading and writing takes place under rtnl (with no changes). I also removed a possibility to specify the length of the address while adding or deleting unicast address. It's always dev->addr_len. The convertion touched especially e1000 and ixgbe codes when the change is not so trivial.

2009-05-26ixgbe: fix 82598 SFP initialization after driver load.Don Skidmore
If we loaded the driver with out a SFP module plugged in it would leave it in a state that make it later unable to link when a module was plugged in. This patch corrects that by: ixgbe_probe() - moving the check for IXGBE_ERR_SFP_NOT_PRESENT from after get_invariants() to after reset_hw() as now reset_hw() is where this condition will be indentified. ixgbe_reset_hw_82598() - Enable this function to now return IXGBE_ERR_SFP_NOT_PRESENT. ixgbe_identify_sfp_module_generic() - This where the lack of SFP module is detected. Modifications are added to allow a different return value for modules that just haven't been plugged in yet. Other functions were updated to allow correct logging.

The dcbnl interface already supports sending down configurations through rtnetlink that can enable LFC when DCB is enabled, so the driver should take advantage of this. 82598 does not support using LFC when DCB is enabled, so explicitly disable it when we're in DCB mode.

The accumulated data is arranged similar to how jumbo frames are arranged with the exception that other packets can be interlaced inbetween. To overcome this issue a next pointer is included in the written back descriptor which indicates the next descriptor in the writeback sequence.

2009-04-20ixgbe: fix link down initial stateJesse Brandeburg
As reported by Andrew Lutomirski <amluto@gmail.com> All the intel wired ethernet drivers were calling netif_carrier_off and netif_stop_queue (or variants) before calling register_netdevice This is incorrect behavior as was pointed out by davem, and causes ifconfig and friends to report a strange state before first link after the driver was loaded, since without a netif_carrier_off, the stack assumes carrier_on, but before register_netdev, netlink messages are not sent out telling link state. This apparently confused *some* versions of networkmanager.

2009-04-17ixgbe: Fix DCB traffic class mapping for 82599PJ Waskiewicz
The traffic classes in hardware are not symmetrical for Rx and Tx. Rx is every 16 descriptor queues, Tx is not. It runs 32-32-16-16-8-8-8 when running with 8 traffic classes, and runs 64-32-16 when running with 4 traffic classes. This patch fixes the mapping.
