Detailed Description

data structure used to pass information about the scatter-gather list to the LL Layer

The ESGL pages are uncached, have a configurable number of SGL of (min, max) = (1, 10), and are 16-byte aligned. Although the application can configure the page size, the size must be incremented in TBD-byte increments. Refer the hardware documentation for more detail on the format of ESGL structure.
