[PATCH net-next 0/7] net: stmmac: start to shrink memory usage

[Russell King (Oracle)]

Hi,

Start shrinking stmmac's memory usage by avoiding using "int" for
members that are only used for 0/1 (boolean) values, or values that
can't be larger than 255.

In addition, as struct stmmac_dma_cfg is approximately a cache line,
shrinks below a cache line as a result of this patch set, and is
required, there is no point separately allocating this from
struct plat_stmmacenet_data. Embed it into the end of this struct
and set the existing pointer to avoid large wide-spread changes.

Lastly, add documentation for struct stmmac_dma_cfg, and document
the stmmac clocks as best we can given the driver history.
