Subject: [PATCH] bus/fslmc: change the eqcr stashing threshold to 1
Date: Wed, 3 Jan 2018 21:09:04 +0530	[thread overview]
Message-ID: <1514993944-11940-1-git-send-email-nipun.gupta@nxp.com> (raw)

Changing the EQCR stashing threshold boosts the performance
of l3fwd application on LS2088 by more than 20% as it helps
in burst packet processing at the Tx side. CPU is immediately
informed about the empty EQCR entries once consumed by the
hardware.
