ixgbe: driver for Intel(R) 82598 PCI-Express 10GbE adapters (v4)
This patch adds support for the Intel 82598 PCI-Express 10GbE chipset. Devices will be available on the market soon. This version of the driver is largely the same as the last release: * Driver uses a single RX and single TX queue, each using 1 MSI-X irq vector. * Driver runs in NAPI mode only * Driver is largely multiqueue-ready (TM) Changes since 20070803: * removed wrappers for hardware functions * incorporated e1000e-style HW api reorganization code * sparse/checkpatch cleanups, namespace cleanups * driver prints out extra debugging information at load time identifying adapter board number, mac, phy types * removed ixgbe_api.c, ixgbe_api.h, ixgbe_osdep.h * driver update to 1.1.18 * removed ixgbe.txt which contained no useful info anymore [ Integrated napi_struct changes from Auke as well... -DaveM ] Signed-off-by: Auke Kok <auke-jan.h.kok@intel.com> Signed-off-by: Ayyappan Veeraiyan <ayyappan.veeraiyan@intel.com> Signed-off-by: Jeff Garzik <jeff@garzik.org> Signed-off-by: David S.
