Michael Brown 92b46b7858 [intelxl] Choose to operate in non-PXE mode The physical function defaults to operating in "PXE mode" after a power-on reset. In this mode, receive descriptors are fetched and written back as single descriptors. In normal (non-PXE mode) operation, receive descriptors are fetched and written back only as complete cachelines unless an interrupt is raised. There is no way to return to PXE mode from non-PXE mode, and there is no way for the virtual function driver to operate in PXE mode. Choose to operate in non-PXE mode. This requires us to trick the hardware into believing that it is raising an interrupt, so that it will not defer writing back receive descriptors until a complete cacheline (i.e. four packets) have been consumed. We do so by configuring the hardware to use MSI-X with a dummy target location in place of the usual APIC register. Signed-off-by: Michael Brown <mcb30@ipxe.org>		5 jaren geleden
