From cc43a8afa8e37cd466000ee1b4995e8f8e7b615d Mon Sep 17 00:00:00 2001 From: Atul Gupta Date: Fri, 30 Nov 2018 14:31:48 +0530 Subject: [PATCH] crypto: chcr - small packet Tx stalls the queue commit c35828ea906a7c76632a0211e59c392903cd4615 upstream. Immediate packets sent to hardware should include the work request length in calculating the flits. WR occupy one flit and if not accounted result in invalid request which stalls the HW queue.
