data structure is used to pass information about the extended scatter-gather list (ESGL) to the LL Layer
The agsaEsgl_t data structure is used to pass information about the extended scatter-gather list (ESGL) to the LL Layer.
When ESGL is used, its starting address is specified the first descriptor entry (i.e. descriptor[0]) in agsaSgl_t structure.
The ESGL pages are uncached, have a fixed number of SGL of 10, and are 16-byte aligned. Refer the hardware documentation for more detail on ESGL.
