2009-02-24ixbge: fix bug when using large pages and jumbo framesJesse Brandeburg
it was pointed out on the list that ixgbe was failing when using 64kB pages and large 16kB MTU. since with a 64kB PAGE_SIZE MAX_SKB_FRAGS = 3, the way the driver was configuring page usage was assuming 2kB is half a page, and was only ever dmaing that much data to a half page. (16kB - header size) / 2048 = 7 or 8 pages, which would far exceed 3 adjust the driver to account for these large pages, the hardware can support DMA to up to 16kB for each descriptor.

2009-02-24ixgbe: Move ring features into an enum, allowing easier future maintenanceShannon Nelson
From: Shannon Nelson <shannon.nelson@intel.com> The ring_feature member of ixgbe_adapter is statically allocated based on the supported features of the device. When a new feature is added, we need to manually update the static allocation. This patch makes the feature list an enum, eliminating the need for multiple updates to the code when adding a new feature.

2009-02-21ixgbe: fix for 82598 Si errata causing buffer overflowDon Skidmore
The failure happens when an interrupt occurs and the driver is reading EICR. This read will cause a clear-by-read which leads to two TLP being inserted in the PCIe retry buffer leading to an overflow of the buffer and corruption of TLPs. The solution is different depending where the reading of EICR takes place. For ixgbe_msix_lsc() since we are in MSIX mode and know OCD is enabled a clear-by-write is done instead of the normal clear-by-read. For ixgbe_intr() 0xffffffff is written to EIMC before the read, masking the interrupts.

Now that our set_num_queues() routines for each feature are re-entrant, and can be called at any point, they shouldn't zero out the feature's indices or mask bits.

2008-11-20netdev: add more functions to netdevice opsStephen Hemminger
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 <shemminger@vyatta.com> Signed-off-by: David S.
