Detailed Description

Efx bitfield access.

Efx NICs make extensive use of bitfields up to 128 bits wide. Since there is no native 128-bit datatype on most systems, and since 64-bit datatypes are inefficient on 32-bit systems and vice versa, we wrap accesses in a way that uses the most efficient datatype.

The NICs are PCI devices and therefore little-endian. Since most of the quantities that we deal with are DMAed to/from host memory, we define our datatypes (efx_oword_t, efx_qword_t and efx_dword_t) to be little-endian.
