Detailed Description

Etherfabric bitfield access.

Etherfabric 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 (efab_oword_t, efab_qword_t and efab_dword_t) to be little-endian.

In the less common case of using PIO for individual register writes, we construct the little-endian datatype in host memory and then use non-swapping equivalents of writel/writeq, rather than constructing a native-endian datatype and relying on the implicit byte-swapping done by writel/writeq. (We use a similar strategy for register reads.)

Extract bit field portion [low,high) from the native-endian element which contains bits [min,max).

For example, suppose "element" represents the high 32 bits of a 64-bit value, and we wish to extract the bits belonging to the bit field occupying bits 28-45 of this 64-bit value.

Then EFAB_EXTRACT ( element, 32, 63, 28, 45 ) would give

( element ) << 4

The result will contain the relevant bits filled in in the range [0,high-low), with garbage in bits [high-low+1,...).
