* ixgbe: use different context for tso and offloadPJ Waskiewicz2008-09-03
| | | | | | | | | | | Change TSO offloads to use a different context than VLAN insertion and Tx checksumming. Hardware has separate registers internally for storing these so use them.

* ixgbe: update dca to new interface, fix CONFIG_DCA_MODULEJesse Brandeburg2008-09-03
| | | | | | | | | | | | | DCA related fixes ================= - ixgbe was not compiling and using DCA correctly if dca was a module - DCA interface changed with new kernel - ixgbe was not correctly configured to indicate DCA hints to the correct CPU.

* ixgbe: should not use HW_CSUM, should use IP* flagsJesse Brandeburg2008-09-03
| | | | | | | | | | as mentioned by Herbert, our hardware supports IP offloads, not full checksum offloads for any protocol in existence (even though the hardware just provides generic csum support over any range of bytes) 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>
* ixgbe: Lock RSS seed, move rx_buf_len to the rx_ringJesse Brandeburg2008-09-03
| | | | | | | | | | | This locks the seed down so loading/unloading the driver will present predictable hashing from RSS. Also move the rx_buf_len out of the adapter struct, and into the Rx ring struct.

* ixgbe: fix rx csum return status misinterpretationJesse Brandeburg2008-09-03
| | | | | | | | | | | | the driver was misinterpreting rx_csum return value in the descriptor so occassionally we would indicate an rx_csum error in our stats when there was none. This would have no effect on traffic because we would just hand the packet to the stack anyway without the offload flag set, but would increase CPU for those packets that needed a recompute.
