-Subject: [PATCH] staging/fsl_qbman: Calculate valid bit from MC-RR
-
-Use the management commmand response registers to determine
-the next expected valid bit when initializing a software
-portal. This avoids using the wrong valid bit in cases
-where a command was partially written but then not
-completed.
