2008-07-22ixgbe: remove device ID for unsupported deviceJesse Brandeburg
The ixgbe driver was untested with device ID 8086:10c8 but still advertises support. Currently if this device is present in the system when the driver is loaded, the system will panic. Remove this device ID until full support can be tested with available hardware. This patch is necessary for 2.6.24, 2.6.25 and 2.6.26 Signed-off-by: Jesse Brandeburg <jesse.brandeburg@intel.com> Signed-off-by: Jeff Kirsher <jeffrey.t.kirsher@intel.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>

2008-07-22netdev: bunch of drivers: avoid WARN at net/core/dev.c:1328Anton Vorontsov
The drivers were touching net queue before it has been started, so without this patch, the drivers will potentially WARN at net/core/dev.c:1328. I don't have the hardware for the drivers below, so this patch is untested, and thus should be carefully peer reviewed. tc35815.c au1000_eth.c bfin_mac.c macb.c ^ The four drivers are using phylib, they're calling netif_start_queue() in open() callback. So trivially remove netif_tx_schedule_all(). Phylib will handle netif_carrier_*(). cpmac.c fec_mpc52xx.c fs_enet/fs_enet-main.c sh_eth.c ^ The same as above, but these were also needlessly calling netif_carrier_*() functions. So removed queue calls and also remove carrier calls, since phylib will handle it. fs_enet-main.c also didn't call netif_start_queue() at open(), this is fixed now.

2008-07-22netxen: cut-through rx changesDhananjay Phadke
NX3031 supports cut-through operation where ingress packets are directly dma'ed into host buffers to reduce latency. This requires larger dma buffers (2kb) and different alignemnt. The buffer posting logic is changed a bit. The free rx buffers are maintained in linked list, since the received reference handles can be out of order. However rx descriptors are still posted sequentially, indexed by producer. Signed-off-by: Dhananjay Phadke <dhananjay@netxen.com> Signed-off-by: Jeff Garzik <jgarzik@redhat.com>
2008-07-22netxen: mtu, mac, link status changesDhananjay Phadke

2008-07-22IB/mthca: Keep free count for MTT buddy allocatorRoland Dreier
MTT entries are allocated with a buddy allocator, which just keeps bitmaps for each level of the buddy table. However, all free space starts out at the highest order, and small allocations start scanning from the lowest order. When the lowest order tables have no free space, this can lead to scanning potentially millions of bits before finding a free entry at a higher order. We can avoid this by just keeping a count of how many free entries each order has, and skipping the bitmap scan when an order is completely empty. This provides a nice performance boost for a negligible increase in memory usage. Signed-off-by: Roland Dreier <rolandd@cisco.com>
