[Date Prev][Date Next][Thread Prev][Thread Next][Date Index][Thread Index] [Xen-devel] [PATCH 10/11] kernel compatibility code
This version of ixgbe has been written to the current upstream kernel
API. This header file defines data structures and functions to allow
the driver to function on older kernels.
