[PATCH 10/12] fsl/fman: Add FMan SP support

Igal.Liberman igal.liberman at freescale.com
Wed Jun 10 18:03:39 AEST 2015


From: Igal Liberman <Igal.Liberman at freescale.com>

Add Storage Profiles support.
The Storage Profiles contain parameters that are used by the FMan in
order to store frames being received on the Rx ports, or to
determine the parameters that affect writing the Internal Context
in the frame margin on Tx.
